At Er~(3+) doping concentration range 0.1-1.5 mol%, Er~(3+) first arrived at ~4F_(7/2) energy level by excited state absorption, then rapidly relaxed to ~2H_(11/2) and ~4S_(3/2) energy levels, the population of which increased, the remarkable upconversion green emission was obtained when Er~(3+) directly went back to ground state by radiative transition.

Er~(3+)浓度在0.1-1.5 mol％时，Er~(3+)通过激发态吸收跃迁到~4F_(7／2)能级，后迅速无辐射弛豫到~2H_(11／2)、~4S_(3／2)能级，~2H_(11／2)和~4S_(3／2)能级上Er~(3+)的布居数增多，Er~(3+)直接辐射跃迁回基态，上转换发射以绿光为主。
