【Abstract】 CaS∶Cu,Eu is known as an optical down conversion additive applied to preparing plastic film for agriculture. The samples were prepared by a hightemperature solid phase reaction procedure in different conditions, and investigated by xray photoelectron spectroscopy and photoluminescence technique. The information on the relationship between the conversion efficiency, stability and the preparation condition has been obtained. It is useful for the preparation of a down conversion transmission material with an increased conversion efficiency.更多还原
