Microstructure and UV Fluorescence of Amorphous I/Au Composite Nanofilms Based on LVDCS Method
The amorphous I/Au composite nanoflms 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 fuorescence emission (λ em max) of I/Au nanoflms was observed at wavelength of 375 nm, and the intensity of fuorescence emission peak of annealed I/Au flms 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 nanoflms is larger than that of the unannealed one. This work also developed a new way to grow I/Au composite fuorescent thin flms.
