摘要

研究了Y1 - xScxPO4: 0.5 mol % Eu3+ (x = 0,0.2, 0.4, 0.5, 0.6, 0.8, 1)固溶体在紫外和真空紫外激发下的发光特性。固溶晶体结构的无序性影响了Eu3+发光光谱的结构。带隙宽度与固溶体组成呈非线性关系。提出了解释这种效应的模型。

Luminescent Properties of Yttrium–Scandium Phosphate Solid Solutions Doped with Europium Ions

The luminescent properties of Y_1 – _xSc_xPO₄: 0.5 mol % Eu³⁺ (x = 0, 0.2, 0.4, 0.5, 0.6, 0.8, 1) solid solutions are studied at the excitation by the radiations of ultraviolet and vacuum-ultraviolet ranges. The disordering of the solid-solution crystal structure is shown to influence the structure of the Eu³⁺ luminescence spectra. The bandgap width is shown to nonlinearly depend on the solid solution composition. The model explaining this effect is proposed.
