利用熔融淬火法在900 ℃下成功制备出原料比为60TeO2-10CaF2-25H3BO3-1Er2O3-4Yb2O3的Er3+/Yb3+共掺杂透明玻璃陶瓷。利用XRD和TEM验证了玻璃陶瓷中存在Er2Te5O13纳米微晶, 并由Raman测试得知其声子能量为886 cm-1。分别测量了其上转换和下转换发射谱, 发现不同激发光源下的发光过程中红、绿光发射强度有明显不同, 并分别对其能量传递过程进行了讨论。

Optically transparent Er3+/Yb3+ codoped glass ceramics based on the system 60TeO2-10CaF2-25H3BO3-1Er2O3-4Yb2O3 have been successfully prepared by melt-quenching method at 900 ℃.The Er2Te5O13 nanocrystals, whose phonon energy was 886 cm-1 by Raman measurement, were characterized by XRD and TEM in the tellurite glass ceramics. Both up-conversion and down-conversion emission spectra were measured. The red and green emissions have different luminescent processes under different excitation sources. The energy transfer processes were discussed individually.
