【Abstract】 An optical transition additive used in farmfilmwas synthesized by doping the Cu and Eu activators into an inorganic fluorescent material,CaS with the high-temperature solid phase reduction method under unˉprotected 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.更多还原
