Nano Ag-ITO films with Ag volume fraction of 0.3%-1.0% were prepared by radio-frequency magnetron co-sputtering and analyzed by X-ray diffraction,scanning electron microscopy and ultraviolet-visible spectroscopy.Microstructure analysis shows that the films are composed of polycrystalline ITO matrix embedded with Ag nanoparticles with a mean size of 60-100 nm.Transmissivity spectra of Ag-ITO films indicate that the visible light transmissivity of the films decreases with increasing the Ag fraction.The transmissivity of the annealed films is higher than that of the as-deposited films.The volume 0.3% Ag-ITO films have the highest light reflectance.The annealed films exhibit lower light absorptance than as-deposited films.A surface plasmon resonance(SPR) peak of volume 0.3% Ag-ITO films is located around 510 nm.Compared with the annealed ITO film,the annealed volume 0.3% Ag-ITO film shows 10% higher reflectivity,while its transmittance is almost the same as that of the annealed ITO film,indicating its potential application in new-type transflective displays.
