XPS Dissection of the Optical Transition Additive in Farm Film

报道了无保护气氛条件下,采用高温固相还原法合成适用于农用塑料地膜的光转换添加剂,共掺铜、铕激活剂的硫化钙(CaS)无机荧光材料,用X射线光电子能谱(XPS)方法对光转换添加剂中不同工艺下激活剂元素进行表征,再通过光致发光谱、透射光谱测量,探索材料中激活剂的能量传输特性,为高新农业的发展提供清洁能源。

An optical transition additive used in farm film was synthesized by doping the Cu and Eu activators into an inorganic fluorescent material, CaS with the high-temperature solid phase reduction method under unprotected atmosphere. The characteristics of the activators in the films prepared under different conditions were measured by X-ray photo-electron spectroscopy. The energy-transfer properties of the activators in the films were investigated by the photo-induced luminescence spectra and transmission spectra. It is useful for developing a clean energy source in agriculture.
