Thermochromic tungsten doped VO2-SiO2 nano-particle synthesized by chemical solution deposition technique

Abstract

Tungsten doped VO2 coated SiO2 nano-particles with mono-dispersion were fabricated by the chemical solution deposition method. The resultant W-doped VO2 coated SiO2 particle size was about 40 nm. The transition temperature of non-doped VO2coated SiO 2 particles was 68°C, and the transition temperature of 1.1 atomic% tungsten doped VO2 coated SiO2 particles was 52°C.©2009 The Ceramic Society of Japan.
