介绍了Cr ~（3+）离子在不同镓浓度的重金属氟化物BIGaZYT玻璃中的光学性质。光谱数据的分析与发射光谱的时间演变允许在这些玻璃中的Cr 3+网站的两个可区分的分布的假设。站点分布和量子效率被发现是镓浓度的函数。
Optical properties of the Cr3+ion in heavy-metal fluoride BIGaZYT glasses with different gallium concentrations are presented. Analysis of the spectroscopic data together with the time evolution of emission spectra allow for the assumption of two distinguishable distributions of Cr3+sites in these glasses. Site distribution and quantum efficiency are found to be a function of gallium concentration.
