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.

摘要

已经开发了用于获得半导体固溶体SnO ₂ + Nb ₂ O ₅ (80:20wt%)和用于制造薄膜纳米级电阻传感器的技术。已经研究了传感器对各种浓度的液化石油气 (LPG) 的气敏特性。当暴露于紫外线辐射时，SnO ₂ ❬Nb❭ 传感器在 250°C 的工作温度下检测对 LPG 的敏感性。选择 250°C 作为工作温度，在该温度下，所研究的传感器对目标气体表现出高灵敏度、操作速度和可重复性。SnO ₂ ❬Nb❭ 结构可用于安全系统以检测 LPG 并确定其浓度。
