Аннотация: Low temperature luminescence spectrum of holmium ions in monoclinic Rb2KHoF6 crystal was found to be well analyzable by the comparison with earlier studied cubic Cs2NaHoF6. The manifestation of the local symmetry influence on the strength of individual lines is found to be distinctive. In the absence of structural data, the local symmetry of holmium in Rb2KHoF6 is proved to be a non-centrosymmetric one. The concentration quenching of holmium luminescence in Rb2KHoF6 is found to be rather modest.

Аннотация: A comparative study was performed of the low-temperature high-resolution absorption spectra of the Yb3+ probe in R1−xYbxAl3(BO3)4 (R = Y, Tm, Lu) crystals grown by flux technique independently in four different laboratories using different solvents. We show that the incorporation of solvent components into the crystal in the course of crystallization gives rise to spectral satellites of the Yb3+ 0(2F7/2) → 0′(2F5/2) absorption lines and assign particular satellites to the Yb3+ centers near the bismuth and molybdenum impurities (which decrease the transparency of YAB in the UV spectral range). We suggest this spectroscopic method for a rapid analysis of the quality of UV laser crystals and for improvement of growth technologies.

Structural and luminescence properties of yellow-emitting NaScSi 2O6:Eu2+ phosphors: Eu2+ Site preference analysis and generation of red emission by codoping Mn2+ for white-light-emitting diode applications / Z. Xia [et al.] // J. Phys. Chem. C. - 2013. - Vol. 117, Is. 40. - P. 20847-20854DOI 10.1021/jp4062225. - Cover image: Artwork representing main idea of this article
Аннотация: The structural properties of clinopyroxene NaScSi2O6 have been investigated using the X-ray powder diffraction refinement, and the luminescence properties of Eu2+ and Eu2+/Mn 2+-activated NaScSi2O6 have been studied to explore the new materials for phosphor-converted white light ultraviolet light-emitting diodes (UV-LEDs). Eu2+ was introduced into the NaScSi2O6 host in the reducing atmosphere, and the preferred crystallographic positions of the Eu2+ ions were determined based on the different structural models of the NaScSi2O6 host. The as-obtained NaScSi2O6:Eu2+ phosphor shows greenish yellow emission with the broad-band peak at 533 nm, and efficient energy transfer (ET) takes place between Eu2+ and Mn2+ in NaScSi2O6, leading to a series of color-tunable phosphors emitting at 533 and 654 nm for the designed NaScSi2O 6:Eu2+,Mn2+ phosphors under excitation at 365 nm. The ET mechanism of Eu2+ and Mn2+ has also been evaluated. We have demonstrated that NaScSi2O6:Eu 2+ and NaScSi2O6:Eu2+,Mn 2+ materials exhibit great potential to act as the effective phosphors for UV-LEDs. В© 2013 American Chemical Society.

Аннотация: Single crystal of ErAl3(BO3)4 was grown and its structure was studied. Polarized absorption spectra of ErAl3(BO3)4 single crystal were measured in the spectral range 1670–330 nm (6000–30000 cm−1). The Judd–Ofelt spectroscopic parameters have been determined: Ω2 = 4.87 × 10−20 cm2, Ω4 = 2.49 × 10−20 cm2, Ω6 = 2.72 × 10−20 cm2. These parameters have been used to calculate the radiative transition probabilities, the multiplet luminescence branching ratios and the fluorescence life times of the manifolds. The luminescence spectra due to transitions 2H11/2 → 4I15/2 (526 nm), 4S3/2 → 4I15/2 (548 nm), 4F9/2 → 4I15/2 (662 nm), 2H11/2 → 4I13/2 + 4I9/2 → 4I15/2 (800 nm) and 4S3/2 → 4I13/2 (855 nm) were recorded in α, σ and π polarizations. The most intensive luminescence belonged to 4S3/2 → 4I15/2 transition (548 nm).
Поляризованные спектры поглощения ErAl3 (BO3) 4 монокристалла были измерены в спектральном диапазоне 1670-330 нм (6000-30000 см-1). Спектроскопические параметры Джадда-Офельта были определены как: Ω2 = 4,87 • 10-20 см2, Ω4 = 2.49 • 10-20 см2, Ω6 = 2,72 • 10-20 см2. Параметры были использованы для расчета вероятностей излучающих переходов, мультиплетные отношения люминесценции раскола и времена жизни мультиплетов. Спектры люминесценции за счет переходов 2П11 / 2 → 4I15 / 2 (526 нм), 4S3 / 2 → 4I15 / 2 (548 нм), 4F9 / 2 → 4I15 / 2 (662 нм), 2П11 / 2 → 4I13 / 2 + 4I9 / 2 → 4I15 / 2 (800 нм) и 4S3 / 2 → 4I13 / 2 (855 нм) были записаны в α, σ и π поляризации. Наиболее интенсивное свечение принадлежало переходу 4S3 / 2 → 4I15 / 2 (548 нм).

Аннотация: Tuning and optimizing luminescent properties of oxonitridosilicates phosphors are important for white light-emitting diode (WLED) applications. To improve the color rendering index, correlated color temperature and thermal stability of layer-structured MSi2O2N2:Eu (M = Sr, Ba) phosphors, cation substitutions have been used to adjust their luminescent properties. However, the underlying mechanisms are still unclear. In this research, a series of (Sr1-xBax)Si2O2N2:Eu (0 ≤ x ≤ 1) compounds were prepared by solid-state reaction, after which systematic emission variations were investigated. The crystal structures of (Sr1-xBax)Si2O2N2:Eu (0 ≤ x ≤ 1) are nominally divided into three sections, namely, Phase 1 (0 ≤ x ≤ 0.65), Phase 2 (0.65 x 0.80), and Phase 3 (0.80 ≤ x ≤ 1) based on the X-ray diffraction measurements. These experimental results are further confirmed by optimizing the crystal structure data with first-principle calculations. Continuous luminescence adjustments from green to yellow are observed in Phase 1 with gradual replacement of Sr2+ with Ba2+, and the abnormal redshift is clarified through extended X-ray absorption fine structure analysis. Sr(Eu)-O/N bond length shrinkage in local structure causes the redshift emission, and the corresponding luminescence mechanism is proposed. Controllable luminescence in Phase 2 (from blue to white) and Phase 3 (from cyan to yellowish green) are observed. Based on the high-resolution transmission electron microscopy and selected area electron diffraction analysis, the two kinds of luminescence tuning are attributed to phase segregation. This study serves as a guide in developing oxonitride luminescent materials with controllable optical properties based on variations in local coordination environments through cation substitutions.

Аннотация: The microcrystals of monoclinic europium molybdate, alpha-Eu-2(MoO4)(3), have been fabricated by solid-state synthesis at T = 753-1273 K for 300 h. The crystal structure of alpha-Eu-2(MoO4)(3) has been refined by the Rietveld method and was found to belong to the space group C2/c with unit cell parameters a = 7.5576(1), b = 11.4709(2), c = 11.5158(2) angstrom, and beta = 109.278(1)degrees (R-B = 3.39%). About 40 narrow Raman lines have been observed in the Raman spectrum of the alpha-Eu-2(MoO4)(3) powder sample. The luminescence spectra of alpha-Eu-2(MoO4)(3) under excitation at 355 and 457.9 nm reveal domination of induced electric dipole transition D-5(0) - F-7(2) and the presence of ultranarrow lines at D-5(0) - F-7(0) and D-5(1) - F-7(0) transitions.

Аннотация: New compound discovery is of interest in the field of inorganic solid-state chemistry. In this work, a whitlockite-type structure Sr1.75Ca1.25(PO4)2 newly found by composition design in the Sr3(PO4)2–Ca3(PO4)2 join was reported. Crystal structure and luminescence properties of Sr1.75Ca1.25(PO4)2:Eu2+ were investigated, and the yellow-emitting phosphor was further employed in fabricating near-ultraviolet-pumped white light-emitting diodes (w-LEDs). The structure and crystallographic site occupancy of Eu2+ in the host were identified via X-ray powder diffraction refinement using Rietveld method. The Sr1.75Ca1.25(PO4)2:Eu2+ phosphors absorb in the UV–vis spectral region of 250–430 nm and exhibit an intense asymmetric broadband emission peaking at 518 nm under λex = 365 nm which is ascribed to the 5d–4f allowed transition of Eu2+. The luminescence properties and mechanism are also investigated as a function of Eu2+ concentration. A white LED device which is obtained by combining a 370 nm UV chip with commercial blue phosphor and the present yellow phosphor has been fabricated and exhibit good application properties.

Аннотация: Scheelite related alkali-metal rare-earth double molybdate compounds with a general formula of ALn(MoO4)2 can find wide application as red phosphors. The crystal chemistry and luminescence properties of red-emitting CsGd1−xEux(MoO4)2 solid-solution phosphors have been evaluated in the present paper. A detailed analysis of the structural properties indicates the formation of isostructural scheelite-type CsGd1−xEux(MoO4)2 solid-solutions over the composition range of 0 ≤ x ≤ 1. The photoluminescence emission (PL) and excitation (PLE) spectra, and the decay curves were measured for this series of compounds. The critical doping concentration of Eu3+ is determined to be x = 0.6 in order to realize the maximum emission intensity. The emission spectra of the as-obtained CsGd(1−x)Eux(MoO4)2 phosphors show narrow high intensity red lines at 592 and 615 nm upon excitation at 394 or 465 nm, revealing great potential for applications in white light-emitting diode devices.

Аннотация: The Eu3+-doped red-orange emitting phosphor of tellurite glass 0.25Li2O–0.20Y2O3–0.5TeO2–0.05Eu2O3 has been synthesized by the melt quenching method. The amorphous nature of the glass has been verified by XRD measurements. The photoluminescence excitation and emission spectra, the luminescence decay curves have been investigated for the composition. The phosphor can be efficiently excited by the near UV light to realize the intense narrow red emission line (611 nm) corresponding to forced electric dipole transition 5D0 → 7F2 of Eu3+ ions. The Li2O–Y2O3–TeO2:Eu3+glass phosphor is a potential red-orange emitting candidate for the application in WLEDs.

Аннотация: A new blue-emitting phosphor Li3Sc2(PO4)3:Eu2+ was synthesized by a high temperature solid-state reaction method, and the crystal structure and photoluminescence properties were investigated in detail. The preferred crystallographic position of the Eu2+ ions in the Li3Sc2(PO4)3 host were determined from the structural analysis and spectroscopic properties. The as-prepared phosphor gave an intense blue emission band centered at 439 nm with the CIE coordinate of (0.1540, 0.0317) upon the excitation of the near ultraviolet light. The critical quenching concentration of Eu2+ in Li3Sc2(PO4)3:Eu2+ was about 15 mol%, and the corresponding concentration quenching mechanism was verified to be the dipole-quadrupole interaction. The fluorescence lifetime of Eu2+ emission and the thermal stable luminescence property have been investigated. Li3Sc2(PO4)3:Eu2+ was found to be a promising candidate as a blue-emitting n-UV convertible phosphor for the application in white light emitting diodes (w-LEDs).

Аннотация: Cation substitution dependent tunable bimodal photoluminescence behavior was observed in the Ca3-xSrx(PO4)2:Eu2+ (0 ≤ x ≤ 2) solid solution phosphors. The Rietveld refinements verified the phase purity and whitlockite type crystal structure of the solid solutions. The tunable photoluminescence evolution was studied as a function of strontium content, over the composition range 0.1 ≤ x ≤ 2. In addition to the emission band peak at 416 nm in Ca3(PO4)2:Eu2+, the substitution of Ca2+ by Sr2+ induced the emerging broad-band peak at 493-532 nm. A dramatic red shift of the emission peak located in the green-yellow region was observed on an increase of x in the samples with 0.75 ≤ x ≤ 2.00. The two emission bands could be related to the EuOn-Ca9 and EuOn-Ca9-xSrx emitting blocks, respectively. The values for the two kinds of emitting blocks in the solid solutions can be fitted well with the observed intensity evolution of the two emission peaks.

Аннотация: A novel blue-emitting double-phosphate phosphor Cs0.72Ca0.72Gd1.28(PO4)(2):Eu2+ was synthesized by the sol-gel method, and the structure and luminescence properties were investigated in detail. The crystal structure and chemical composition of Cs0.72Ca0.72Gd1.28(PO4)(2) matrix was analyzed and determined based on Rietveld refinements and phase and chemical composition analysis. The composition-optimized Cs0.72Ca0.72Gd1.28(PO4)(2):Eu2+ exhibited strong blue light, peaking at 462 nm upon excitation at 365 nm with the CIE coordinates of (0.139, 0.091). The quenching concentration of Eu2+ in the Cs0.72Ca0.72Gd1.28(PO4)(2) phase was about 0.01 and attributed to the dipole-quadrupole interaction. The thermally stable luminescence properties, fluorescence decay curves and diffuse reflectance spectra of Cs0.72Ca0.72Gd1.28(PO4)(2):Eu2+ phosphors are also discussed, all of which indicate that the Cs0.72Ca0.72Gd1.28(PO4)(2):Eu2+ phosphor is a promising phosphor for application in white-light UV LEDs.

Аннотация: The Judd–Ofelt theory has been applied to analyze absorption spectra of Ho3+ ion in HoAl3(BO3)4 measured in spectral range 300–700 nm at room temperature. The Judd–Ofelt spectroscopic parameters have been determined as: Ω2 = 18.87 x 10 -20 cm2, Ω4 = 17.04 x 10 -20 cm2, Ω6 = 9.21 x 10 -20 cm2. These parameters have been used to calculate radiative lifetimes and branching ratios of the luminescence manifolds. Three luminescent bands were found in the spectral range 450–700 nm ascribed to transitions from the 5F5, (5F4, 5S2) and 3K8 states to the ground state 5I8. Experimental intensities of these luminescence transitions were compared with those calculated by using Judd–Ofelt theory and the system of kinetic equations for populations of starting luminescing states. Probabilities of radiativeless transitions were evaluated from this comparison.

Аннотация: β-RbNd(MoO4)2 microplates have been prepared by the multistage solid state synthesis method. The phase composition and micromorphology of the final product have been evaluated by XRD and SEM methods. The electronic structure of β-RbNd(MoO4)2 molybdate has been studied employing the X-ray photoelectron spectroscopy (XPS) and X-ray emission spectroscopy (XES). For the molybdate, the XPS core-level and valence-band spectra, as well as XES bands representing energy distribution of the Mo 4d- and O 2p-like states, have been measured. It has been established that the O 2p-like states contribute mainly to the upper portion of the valence band with also significant contributions throughout the whole valence-band region. The Mo 4d-like states contribute mainly to a lower valence band portion
