研究了卤化铅调整Tm^3+／Yb^3+共掺碲酸盐玻璃的热稳定性能、Raman光谱和上转换发光光谱，分析了Tm^3+／Yb^3+共掺氧卤碲酸盐玻璃的上转换发光机理．结果发现：混合卤化铅调整Tm^3+／Yb^3+共掺碲酸盐玻璃具有好的热稳定性能、低的声子能量、强的上转换蓝光．这表明混合卤化铅调整Tm^3+／Yb^3+共掺碲酸盐玻璃是一种上转换蓝光激光器的潜在基质材料．

The thermal stability, Raman spectra, and upconversion luminescence spectra of lead halide-modified Tm-3/Yb3+-codoped tellurite glasses have been investigated, and the upconversion luminescence mechanism of Tm3+/Yb3+-codoped oxyhalide tellurite glasses were analyzed. The results showed that mixed lead halide-modified Tm3+/Yb3+-codoped tellurite glasses possess good thermal stability, low phonon energy and intense upconversion blue luminescence, which indicates that mixed lead halide-modified Tm3+/Yb3+-codoped tellurite glasses can be used as a kind of potential host materials for upconversion blue lasers.
