Abstract:
Large-scale uniform Ag@TiO2 films was prepared by RF magnetron sputtering in pure Ar plasma using polycrystalline TiO2 semiconductor sintered target. The effect of annealing on the photochromic properties was studied to obtain a better understanding of the interaction of the structure. Ultraviolet-visible absorption and scanning electron microscopy were performed to investigate the possibility of tailoring the structure with consequent modification of the optical properties. Ag nanoparticles were formed between TiO2 films after annealing the samples with Ag film structure. The annealed Ag@TiO2 films present a photochromic property in comparison with the as-prepared samples. Such nanocomposite films can be used as smart windows, high density multiwavelength optical memory and rewritable electronic paper. © (2013) Trans Tech Publications, Switzerland.
