Аннотация: The structures of K 2(1-x)Rb 2xAl 2B 2O 7, x = 0.25, 0.5, 0.75, have been determined in space group P321 through Rietveld analysis of X-ray powder diffraction data. The solubility limit in K 2(1-x)Rb 2xAl 2B 2O 7 crystals has been estimated as x similar to 0.83-0.9. Nonlinear optical properties of KRbAl 2B 2O 7 have been verified by powder Kurtz-Perry method. Mechanisms of structural parameter variation in K 2Al 2B 2O 7 crystal family have been discussed.

Аннотация: Rubidium neodymium dimolybdate, RbNd(MoO4)(2), microcrystals have been fabricated by solid state synthesis at T=550-600 degrees C by t=324 ks. Crystal structure of RbNd(MoO4)(2) has been refined by Rietveld method in space group Pbcn with cell parameters a = 5.1772(1) angstrom, b = 18.7293(4) angstrom, and c = 8.2774(1) angstrom (R-B=5.05%). The crystal structure of RbNd(MoO4)(2) consists of layers of MoO4 tetrahedrons cornersharing with NdO8 square antiprisms. These layers are perpendicular to b-axis of the unit cell. About 20 narrow Raman lines have been observed in Raman spectrum recorded for RbNd(MoO4)(2) powder sample. (C) 2010 Elsevier B.V. All rights reserved.

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.

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: Absorption spectra of the Nd3+ ions in an orthorhombic δ-BiB3O6 single crystal were measured in the spectral range 11,000-20,500 cm-1. The f-f transition intensities were analyzed in terms of the Judd-Ofelt theory, and the following parameters of the theory were obtained: Ω2 = 6.35 × 10-20 cm2, Ω4 = 4.86 × 10-20 cm 2, and Ω6 = 11.233 × 10-20 cm 2. The strengths, spontaneous emission probabilities, branching ratios, spectroscopic quality factor and excited state radiative lifetime were calculated for laser transitions from the 4F3/2 state to 4IJ manifold. Spectroscopic properties of Nd 3+:δ-BiB3O6 crystal favor lasing at 1.3 μm, where this crystal possesses near non-critical phase matching for second harmonic generation. © 2012 Elsevier B.V.

Аннотация: The refractive index dispersion of the γ-BiB3O6 crystal in the wavelength range 0.43–0.81 μm has been measured. It has been shown that the principal refractive indices n 1, n 2, and n 3 are on average higher than those of α-BiB3O6, but are slightly lower than those of δ-BiB3O6. The temperature dependences of the rotation angle φ(T) of the optical indicatrix and birefringence Δn 2(T) = (n 1 − n 3)(T) have been studied in the temperature range 100–963 K. It has been shown that the γ-BiB3O6 crystal is stable in this temperature region.

Аннотация: The solid-phase synthesis of manganese silicides on the Si(100)2 × 1 surface coated at room temperature by a 2-nm-thick manganese film has been investigated using high-energy-resolution photoelectron spectroscopy with synchrotron radiation. The dynamics of variation of the phase composition and electronic structure of the near-surface region with increasing sample annealing temperature to 600°C, has been revealed. It has been shown that, under these conditions, a solid solution of silicon in manganese, metallic manganese monosilicide MnSi, and semiconductor silicide MnSi1.7 are successively formed on the silicon surface. The films of both silicides are not continuous, with the fraction of the substrate surface occupied by them decreasing with increasing annealing temperature. The binding energies of the Si 2p and Mn 3p electrons in the compounds synthesized have been determined.

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 dispersion of the relative permittivity E of a 27-nm-thick epitaxial Fe3Si iron silicide film has been measured within the E = 1.16-4.96 eV energy range using the spectroscopic ellipsometry technique. The experimental data are compared to the relative permittivity calculated in the framework of the density functional theory using the GGA-PBE approximation. For Fe3Si, the electronic structure and the electronic density of states (DOS) are calculated. The analysis of the frequencies corresponding to the transitions between the DOS peaks demonstrates qualitative agreement with the measured absorption peaks. The analysis of the single wavelength laser ellipsometry data obtained in the course of the film growth demonstrates that a continuous layer of Fe3Si iron silicide film is formed if the film thickness achieves 5 nm.
