农膜转光剂CaS∶Cu,Mn的结构分析
Structural Analysis of CaS∶Cu,Mn Material Used as an Optical Conversion Transmission Additive Applied to Preparing Plastic Film for Agriculture
【摘要】 运用X射线光电子能谱技术,证明CaS∶Cu,Mn荧光材料中铜是以一价的形式存在,锰是以二价的形式存在.测得荧光材料的透射光谱,理论分析认为它们分别由不同价态的铜离子和锰离子产生,透射光谱的测试证实这是理想的农膜转光剂.
【Abstract】 CaS∶Cu,Mn samples were investigated by xray photoelectron spectroscopy. It is established that Cu existed in the Cu+ state and Mn in the Mn2+ state in these samples. The transmission spectrum has been recorded and it is attributed to the contributions by Cu+ and Mn2+ ions. The analysis of the spectrum shows that CaS∶Cu,Mn is a good optical conversion transmission additive in preparing plastic film for agriculture.
