Effects of TiO2 Interlayers on the Optical Switching of VO2 Thin Films Grown by Sol-Gel Process

Abstract

Abstract:

Thermochromic VO₂ and V_xW_1-_xO₂ films were deposited on TiO₂/mica substrates. The TiO₂/mica substrates were fabricated via Sol-Gel process, and the hydrophilicity of the TiO₂/mica substrate was improved under UV light irradiated. The V₂O₅ sol was deposited on the TiO₂/mica substrate by the spin coating method, and then it was annealed. SEM and XRD analysis were applied to analyze the morphology, phases and microstructure of the films. FTIR was used to study the thermochromic properties. The results suggest that VO₂/TiO₂ grow preferentially along single orientation. V_xW_1-_xO₂/TiO₂ composite film is impossible to fabricate single orientation films. TiO₂interlayers are favorable to compact the VO₂ thin films and reduce the transition temperature. It will make the hysteresis width of V_xW_1-_xO₂/TiO₂ composite film reduce to about 4℃ particularly.

Key words: vanadium dioxide film, composite film, Sol-Gel method, photo-hydrophility, thermochromism
