【Abstract】 Luminescence material CaS∶Cu,Eu was prepard by the high temperature solid phase reaction technique and its micro structure was investigated by x ray diffraction and transmission spectrum techniques.The informations on the relation of the conversion efficiency with the bonding state of this material have been obtained. It provides the theoretical basis for the development of down conversion transmission material and corresponding curtain applied in agriculture.更多还原
