【摘要】 本文制备了一种新的Er³⁺/Tm³⁺/Yb³⁺共掺氧卤碲酸盐玻璃,研究了基质玻璃的热稳定性能、Raman 光谱和上转换发光。结果发现,氧卤碲酸盐玻璃具有好的热稳定性能和低的声子能量,在980nmLD 激发下,可同时观察到明显的蓝色（476nm）、绿色（530和545nm）和红色（656nm）上转换发光。上转换蓝光（476nm）是由于Tm³⁺离子¹G4→³H₆跃迁,上转换的绿光（530和545nm）是由于Er³⁺离子²H_11/2→⁴I_15/2和⁴S_3/2→⁴I_15/2跃迁,上转换红光（656nm）是由于Er³⁺离子⁴F_9/2→⁴I_15/2跃迁。研究结果表明Er³⁺/Tm³⁺/Yb³⁺共掺氧卤碲酸盐玻璃是实现三维立体显示较为吸引人的基质材料。更多还原

【Abstract】 Er³⁺/Tm³⁺/yb³⁺-codoped new oxyhalide tellurite glass was prepared in this paper,thermal stability,Raman spectrum and upconversion luminescence of Er³⁺/Tm³⁺/Yb³⁺-codoped oxyhalide tellurite glass were studied.The results show that the oxyhalide tellurite glass has good thermal stability and low phonon energy.The intenseblue（476 nm）,green（530 and 545 nm）and red（656 nm）emissions were simultaneously observed at roomtemperature under 980 nm LD excitation.Upconversion blue（476 nm）luminescence is due to the ¹G₄→³H₆transition of Tin³⁺,upconversion green（530 and 545 nm）and red（656 nm）luminescence are due to the ²H_11/2→⁴I_15/2,⁴S_3/2→⁴I_<sub>15/2,and ⁴F_9/2→⁴I_15/2transitions of Er³⁺,respectively.The studied results indicate that the oxyhalide telluriteglass is potential materials for realization of three-dimensional volumetric display.更多还原
