Preview Abstract
We have prepared Pt-doped WO₃ composite films by sol-gel compounding and DC reactive magnetron sputtering respectively. Spectra change process according to the absorbing hydrogen time has been characterized by UV-VIS, X-ray diffraction spectra of two kinds of samples have been studied in this paper, and the crystallization temperature of film has been observed at the same time. As a result, both two WO₃ composite films are better sensitive to hydrogen by Pt-doping and the Pt sputtered sol-gel film has faster response to hydrogen than the Pt sputtered film by DC reactive magnetron sputtering, but the changes of luminousness are almost equal for two films.
