Abstract
The luminance and the productivity of synthesizing ETM,suchas 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 ultrashout 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.
