摘要

本文报告了从基于 K2Mo3O10 的高温溶液中合成固溶体以及通量生长通式为 La1 - x - yTbxEuyMgB5O10 的单晶体的条件和结果。我们研究了固溶体在 0.2 < x < 0.7 和 0.1 < y < 0.6 范围内的结构特性、组成、热特性、Tb3+ 和 Eu3+ 发光光谱以及激发光谱。我们计算了单晶体的 CIE 发光光谱，并利用它们制造出了可运行的原型发射器。

Luminescence Properties of Tb3+- and Eu3+-Doped Lanthanum Magnesium Pentaborates

In this paper, we report the conditions and results of the synthesis of solid solutions and flux growth of single crystals with the general formula La_{1 −} _x _– _yTb_xEu_yMgB₅O₁₀ from a K₂Mo₃O₁₀-based high-temperature solution. The structural properties, composition, thermal characteristics, Tb³⁺ and Eu³⁺ luminescence spectra, and excitation spectra of the solid solutions have been studied in the ranges 0.2 < x < 0.7 and 0.1 < y < 0.6. We have calculated CIE luminescence spectra of the single crystals and fabricated operating prototype emitters using them.

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
