摘要： 为了寻找新的发光体基质材料,本文研究了(Y1-xLax)2O2S:Tb、(Y1-xGdx)2O2S:Tb和(Gd1-xLax)2O2S:Tb三个二元稀土硫氧化物固溶体的发光。用稀土氧化物高温硫化法合成了试样。研究了这三个二元体系的发光亮度、发射光谱、发光颜色和余辉时间等发光特性随组成的变化规律。

Abstract: In order to seek new host materials of phosphor, three binary systems of rare earth oxysulfides (Y1-xLax)2O2S:Tb, (Y1-xGdx)2O2S:Tb and (Gd1-xLax)2O2S:Tb have been investigated. Samples with various compositions of these systems were prepared by sulfidizing the corresponding mixed rare earth oxides at high temperature.The changes of luminous brightness, emission spectra, chromaticity coordinates of samples with matrix compositions have been studied.
