Study of Gas Sensitivity of SnO2 ❬Nb❭ Film in Liquefied Petroleum Gas

  • Published:
Journal of Contemporary Physics (Armenian Academy of Sciences) Aims and scope

Abstract

A technology has been developed for obtaining a semiconductor solid solution SnO2 + Nb2O5 (80 : 20 wt %) and for manufacturing a thin-film nanoscale resistive sensor. The gas-sensitive characteristics of the sensor to various concentrations of liquefied petroleum gas (LPG) have been investigated. The SnO2❬Nb❭ sensor detects sensitivity to LPG from an operating temperature of 250°C when exposed to ultraviolet radiation. The temperature of 250°C was selected as the working temperature, at which the investigated sensor showed high sensitivity, operation speed and repeatability over time to the target gas. The SnO2❬Nb❭ structure can be used in security systems to detect LPG and determine its concentration.
