Abstract

In the fabrication of films, substrate temperature played the most important role. It decided the phase components of the films. Quaternary component Rb_0.5Cs_0.5Ag₄I₅ thin film was grown by vacuum evaporation on NaCl crystalline substrates. A series of thin films were synthesized at different substrate temperature, and the topographical images of these films were obtained by scanning electron microscope, and their exciton spectra were measured at 80K by UV-2100 spectrophotometer. It was found that the optimal substrate temperature to grow Rb_0.5Cs_0.5Ag₄I₅ was about 340K, at other temperature, there were other complex multicomponent compounds in the films.
