摘要

Sol-gel process was adoped to prepare Er3- and Yb3+ codoped SiO2 glass DTA and FTIR were carried out to Investigate the structure change from gel to glass The fluorescence emission spectra were measured The green upconversion emission was obtained for the Er3+-Yb3+ codoped sol-gel SiO2 glass The energy transfer between Er3+ ion and Yb3+ ion for the upconversion emission was discussed.
