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.
