The luminance and the productivity of synthesizing ETM, such as CaS∶Eu,Sm and CaS:Ce,Sm, have been risen greatly by utilizing the rare earth direct doped technique, their infrared upconversion efficiency is obtained by using the ultrashort infrared pulse from a pulsed CPM Nd∶YAG laser. Prepared by sulfurizing flux method and the rare earth direct doped technique, stoichiometry of the major activators in ETM is measured by means of ICP MS. The main factors influencing upconversion efficiency of ETM are analyzed.
