Preparation of Nano WO₃-Doped Materials and Optical Properties

Abstract:

As metal oxide semiconductor, tungsten oxide is studied and applied extensively because of its electrochromic property, gasochromic property, photochromic property, and gas sensing property. In this paper, the doped and undoped WO₃ were prepared by the precipitation method and the molten salt method. The crystals were characterized by FT-IR spectrometer and fluorescence spectrometer. The fluorescence spectra showed that the doping lanthanum and strontium can effectively improve the luminescence properties of the product. IR spectra indicated that the products contain WO₃ and H₂O. The photocatalytical degradation of methyl orange under UV light irradiation using WO₃ was investigated, which shows that the iron-doping can effectively improve the WO₃ photocatalytic degradation activity.
