| Abstract: | 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. |
