Abstract

Optical properties of the granular Sn films with coating Al films are studied. The experimental results indicate that the Al coating strongly affects the optical properties of the granular Sn- films, the spectral selectivity of the solar energy in the visible region and the reflectance in the near IR region are enhanced. The filling factor Z of granular Sn films obviously influences the optical properties of the film system. Based on the installed structural model and Maxwell- Garnett theory, the reflective spectra are calculated and the theoretical results fit the experimental ones very well. It's show that the granular Sn films coated with Al have some kind of reflective color, it may be used as decorative mirrors for many purposes.
