Mg_2SiO_4:Cr^(3+)晶体的生长及其特性

Growth and characterization of Mg_2SiO_4:Cr^(3+) single crystals

介绍了用提拉法生长的Mg_2SiO_4:Cr^(3+)单晶的生长、结构和形态特征,测定了该晶体的吸收谱和荧光谱。荧光谱电子振动边带在800～1400nm,吸收谱中有一定的Fe^(3+)吸收。

: Mg2SiO4:Cr3+ single crystals were growh by Czoehralski method for the first time in China. Characterization of crystal growth, its structure and morphology wre described. The absorption spectrum and fluorescence spectrum of Mg2SiO4:Cr were measured. Vibronic side band of the fluorescence spectrum in our Cr3+:Mg2SiO4 crystals ranges from 800nm to 1400nm and the absorption band of Fe3+ wore observed.
