Paper Abstract

In this paper, WO3 sol was prepared via the sol-gel method, and palladium chloride powder was dissolved in the sol in different W: Pd molar ratios. Pd doped WO3 films were coated on silicon wafers and ordinary slide glasses by dip-coating method. The grain distribution of WO3 sol doped with PdCl2 was measured by Laser Particle Size Analyzer. Surface morphology and microstructure of WO3 films which doped or undoped with PdCl2 were analyzed by AFM, which show that PdCl2 has an important effect on the structure of the WO3 films. The gasochromic properties of the films are investigated by UV-Vis spectrophotometer. The WO3 films show good gasochromic properties. The effect of concentration of PdCl2 on gasochromic kinetic process of WO3 films was investigated. Finally the modulation of the light transmittance by the gasochromic films was discussed.
