Abstract:In this paper,CaS:Sm3+ ,Eu2- phosphor are firstly synthesized by microwave radiation method(MRM).The materials with submicro-scale(300~400nm) have been characterized by XRD,SEM and the fluorescent spectroscopy. It shows the different concentrations of Sm2+ and Eu2+ differently effects on the fluorescent properties. Sm3+ ion may efficiency enhance the red fluorescence of CaS : Eu2+ phosphor since the energy transfer of Sm3+-Eu2+.
Keywords:rapid synthesis by microwave radiation method  sphere  submicro-scale  energy transfer  luminescence
