中文摘要：

用熔融淬冷方法制备Pr^3＋掺杂的硫卤玻璃（0．64GeS2-0．16Ga2S3-0．2KBr）1-x -PrCl3）x，x=0，0．001，0．003，0．005．对玻璃进行X射线衍射实验分析、差热分析、红外透射光谱、紫外透射光谱的测试，结果分析表明：Pr^3＋掺杂到0．5mol％，都形成良好的玻璃态；掺杂后玻璃的稳定性降低，玻璃的红外透过率增大，截止边不变；玻璃的紫外截止边向短波方向移动；玻璃在588nm处存在吸收峰，对应着Pr^3＋的^3H4→^1D2跃迁．

英文摘要：

Pr^3＋-doped chalcohalide glasses. （0.64GES2-0. 16Ga2S3-0.2KBr）1-x -- （PrCl3）x （x = 0, 0.1,0. 3,0. 5 mol%） were prepared using the conventional melt-quenching technique. The thermal properties, infrared transmission spectra, and -dis-near IR transmission spectra of the samples were investigated. The results indicated： （1） with the increasing addition of PrCl3, the thermal stability decreased; （2） with the content of PrCla increasing, the visible cut-off edge shifted to the shorter wavelength together with the enhanced transmission while no changes occured about the IR multi- phonon absorptive edge in middle-infrared region. The absorptive band near 588 nm was associated with the a ^3H4→^1D2 transition of Pr^3＋.
