AbstractThe colloids of ZnO and WO3 were synthesized and ZnO colloid with different mass fractions was added into the WO3 colloid to get WO3/ZnO composite colloids. The experimental results indicate that the UV-light coloration Of WO3 nanoparticles could be improved greatly after the addition of ZnO. When the molar ratio of ZnO to WO3 is about 1 : 100, the magnitude of the difference of absorbance(DeltaOD) at 900 nm after and before the coloration for WO3/ZnO colloids is as about 135 times as that Of WO3 colloids. The surface photovoltaic spectra show that the state density of the surface state of WO, increases greatly after the addition of ZnO, thus, under the UV-light irradiation more electrons from ZnO nanoparticles can be captured in the surface state and those electrons can be excited to a higher energy level, resulting in the improved coloration.
