powder samples were synthesized with solid-state reacting methods
respectively. The Stocks and Anti-Stocks light-emitting properties with Er
3+
were researched. Dependences of the emission features on excited population processes were exhibited with the spectra obtained following an excitation
respectively
at 980
532 and 408 nm. Effects of local field of doped

charge transfer state (CTS) were observed. Further
the energy-transfer processes between Yb
3+
and Er
3+
based on the energy matching conditions and the Stocks and Anti-Stocks emission mechanism with Er
3+
should be suggested with schematic energy-level schemes.
