Abstract
In the present paper, we study the optical, electrical, and sensing properties of titanium dioxide (TiO2) film deposited on glass plates using a vacuum coating technique (High Hind Vacuum). The optical properties were studied using UV–visible and the result found that the band gap of fabricated thin film is 3.3 eV. The structural properties of the deposited film have been explored by XRD. XRD measurement revealed that the crystallite size is 25.7 nm and it showed that the deposited film is anatase phase and nanometric range. The experimental work was done for the study of LPG sensing properties at 300 K in the laboratory. Results found that the TiO2 film fast response/recovery time (91 s/180 s) and a maximum response of 29 % toward LPG.
