Аннотация: Синтезирован комплекс [Eu(DETBA)3] n (I), HDETBA - 1,3-диэтил-2-тиобарбитуровая кислота (C8H12N2O2S), и методом РСА определена его структура. Кристаллы I триклинные: a = 11,0205(2), b = 11,8811(3), c = 12,7312(2) Å, a = 100,933(1), b = 109,704(1), g = 101,161(1)°, V = 1479,88(5) Å3, пр. гр. P -1, Z = 2. Каждый из трех независимых ионов DETBA- является мостиковым m2-O,O¢-координированным лигандом. Координационный полиэдр Eu(III) представляет искаженный октаэдр. Мостиковые DETBA- объединяют октаэдры в бесконечный двумерный слой. В структуре есть внутримолекулярные водородные связи, но отсутствуют межмолекулярные водородные связи и p-p взаимодействие. Результаты ИК спектроскопии и фотолюминесценции согласуются с данными РСА. Основным продуктом термического разложения I при 900 °С является оксисульфат Eu2O2SO4.

   Перевод заглавия: Изменения структуры и фотолюминесценция люминофоров Lu3(Al,Mg)2(Al,Si)3O12:Ce3+: новый желтый преобразователь голубого света, получаемого от твердотельных светодиодов
Аннотация: This paper reports the development of new phosphors using the chemical unit cosubstituting solid solution design strategy. Starting from Lu3Al5O12, the Al3+-Al3+ couple in respective octahedral and tetrahedral coordination was simultaneously substituted by a Mg2+-Si4+ pair forming the Lu3(Al2-xMgx)(Al3-xSix)O12:Ce3+ (x = 0.5-2.0) series; as a result, the CeO8 polyhedrons were compressed and the emission got red-shifted from green to yellow together with the broadening. The evolution of, the unit cell, the local structural geometry as well as the optical properties of Ce3+ in these garnet creations, in response to the gradual Mg-Si substitution for Al-Al, were studied by combined techniques of structural refinement and luminescence measurements. The new composition Lu2.97Ce0.03Mg0.5Al4Si0.5O12 was comprehensively evaluated regarding its potential application in blue LED-driven solid state white lighting: the maximum emission is at 550 nm under ?ex = 450 nm; the internal and external quantum efficiencies can reach 85% and 49%, respectively; a 1-phosphor-converted wLED lamp fabricated using the as-prepared phosphor exhibits the luminous efficacy of 105 lm W-1, the correlated color temperature of 6164 K and the color rendering index (Ra) of 75.6. The new solid solution composition series is open for further optimization to enhance the competence for commercial consideration. © 2016 The Royal Society of Chemistry.

Аннотация: Dopants in luminescent metal halides provide an alternative way for photoluminescence tuning towards versatile optical applications. Here we report a trivalent antimony (Sb3+)-doped single crystalline 0D metal halide with the composition of (C9NH20)9[Pb3Cl11](ZnCl4)2:Sb3+. This compound possessed the coexistence of two emission centers including intrinsic and extrinsic self-trapped excitons (STEs), which are ascribed to [Pb3Cl11]5− clusters and triplet STEs formed by the 3P1–1S0 transition of Sb3+. By regulating the Sb3+ concentration, the emission can be tuned from green to yellow and finally to orange, which would help to develop optically pumped white light-emitting diodes (WLEDs) with different photometric characteristics. Moreover, this dopant-induced extrinsic STE approach presents a new direction towards tuning the luminescence properties of 0D metal halides, and may find application in environmentally-friendly, high-performance metal halide light emitters.

Аннотация: Discovering new Eu2+-doped red-emitting phosphors in oxide-based materials is a challenge for white light-emitting diode (WLED) applications. Herein, a highly efficient high-frequency induction heating method is employed to rapidly prepare the red-emitting Sr2Sc0.5Ga1.5O5:Eu2+ phosphors peaking at 614 nm and exhibiting a high photoluminescence quantum yield of 78.4% under the excitation of 440 nm. The structural and spectral analyses suggest that Eu2+ ions tend to enter the [Sc1/Ga1O6] and [Ga2O6] polyhedrons with small coordination numbers, leading to the broadband red emission originated from large crystal field splitting of Eu2+ 5d level. The chemical substitution of Ba in the Sr site enhances the thermal stability and helps to the photoluminescence tuning from 614 to 728 nm in SrBaSc0.5Ga1.5O5:Eu2+. The WLED device fabricated by blending the red Sr1.7Ba0.3Sc0.5Ga1.5O5:Eu2+ and yellow Y3(Al, Ga)5O12:Ce3+ phosphors shows a high color-rendering index (Ra = 91.1), and low color-correlated temperature (CCT = 4750 K). This study aims to provide a new synthesis method and design principle for guiding the development of Eu2+-doped oxide-based red phosphors with low preparation cost; moreover, the photoluminescence tuning strategy via cation substitutions is essential to achieve tunable emission, even the near-infrared luminescence.

   Перевод заглавия: Фотолюминесценция тетрагалогенидов марганца(II) и цинка(II) пефлоксацина
Аннотация: Mn2+-based hybrid materials have become the hotspot of current research studies owing to their high photoluminescence quantum yield (PLQY), low-cost, environmental friendliness and stability. For the first time, we report the hydrothermal synthesis of two lead-free zero-dimensional luminescent organic-inorganic hybrid compounds, PefH2[MnBr4] (1) and PefH2[MnCl4] (2) (Pef = pefloxacin). They were characterized by elemental analysis, TG-DSC, single-crystal and powder XRD. Compounds 1–2 exhibit a distorted tetrahedral geometry around the manganese(II) metal center, which is isolated from the same centers by bulky pefloxacindi-ium (PefH22+) ions with a Mn···Mn distance of 7.3 Å. Their structures are stabilized by N—H···O, O—H···X (X = Br, Cl), C—H···O and C—H···X hydrogen bands and π–π stacking interaction. Thermal decomposition starts at T › 230°С for 1 and T › 210°С for 2 and proceeds for several stages. Upon UV excitation compounds exhibit a bright green emission with a moderate PLQY of 45% for 1 and 30% for 2. The influence of the halide ion and metal ion on the photoluminescence properties of isostructural compounds PefH2[MX4] (M = Mn, Zn and X = Br, Cl) is discussed.
