三维立体显示用稀土掺杂氧卤碲酸盐玻璃

制备了一种新的Er^3+／Tm^3+/Yb^3+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。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(530nm和545nm)和红色(656nm)上转换发光。上转换蓝光(476nm)是由于Tm^3+离子1^G4→3^3H6跃迁，上转换的绿光(530nm和545nm)是由于Er^3+离子2^H11/2→4^I15／2和4^S3/2→4^I15/2跃迁，上转换红光(6

A new Er3+/Tm3+/Yb3+-codoped oxyhalide tellurite glass was prepared in this paper, thermal stability, Raman spectrum and up-conversion luminescence of Er3+/Tm3+/Yb3+-codoped oxyhalide tellurite glass were studied. The results show that the oxyhalide tellurite glass has a good thermal stability and a low phonon energy. The intense blue (476 mn), green (530 and 545 nm) and red (656 nm) emissions were simultaneously observed at the room temperature under 980 nm LD excitation. The up-conversion blue (476 nm) luminescence is due to the (1)G(4)->H-3(6) transition of Tm3+, the up-conversion green (530 and 545 nm) and the red (656 nm) luminescence are due to the H-2(11/2)->I-4(15/2), S-4(3/2)->I-4(15/2), and F-4(9/2)->I-4(15/2) transitions of Er3+, respectively. The results indicate that the oxyhalide tellurite glass is potential materials for realization of three-dimensional volumetric display.
