摘要
The amorphous I/Au composite nanofilms were prepared by low vacuum direct current sputtering(LVDCS)method.The optimized preparation technologies contain growth pressure,time,gaseous environment and annealing conditions.The maximum fluorescence emission(λemmax)of I/Au nanofilms was observed at wavelength of 375 nm,and the intensity of fluorescence emission peak of annealed I/Au films was smaller than that of unannealed one due to fewer amorphous Au nanoparticles,caused by annealing treatment.In the UV-Vis absorption spectra,the intensity of UV-Vis absorption peak of annealed I/Au nanofilms is larger than that of the unannealed one.This work also developed a new way to grow I/Au composite fluorescent thin films.
