摘要：
Yttria ceramic as host matrix for different ratio of Er3+ as activator and Yb3+ as sensitizer were obtained through coprecipitation method followed by powders pressing and sintering at 1300 degrees C for 4h. The upconversion photoluminescence spectra were recorded after the ceramic irradiation at 976 nm. The energy levels involved in the emission in the visible range and a mechanism for upconversion process was proposed.
