| Abstract: | 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. |
