摘要

A series of (WO_3)_(1-x)(Nb_2O_5)_x (x = 0,0.05, 0.1 and 0.15) mixed oxide films were fabricated by pulsed laser deposition (PLD) at 27 Pa oxygen partial pressure on 1TO glass substrates. The thickness of the (WO_3)_(1-x)(Nb_2O_5)_x thin films is about 350 ± 30 nm and their surface has a uniform morphology. A layer of platinum (Pt) was then sputtered onto the surface of the film. The hydrogen gas sensing performance of Pt catalyst activated (WO_3)_(1-x)(Nb_2O_5)_x thin films were investigated. The cycling of the coloration was obtained from UV-vis spectra. Gasochromic coloration of (WO_3)_(1-x)(Nb_2O_5)_x thin films were investigated at room temperature in H2-N2 mixtures containing 1-100 mol% of H_2. The results show that the shortest response time of (WO_3)_(1-x)(Nb_2O_5)_x/Pt hydrogen sensor is within 30 s and the highest transmittance change (AT) varies from 20% to 30%.
