Tin dioxide based sensors for the detection of liquified petroleum gas

摘要

Several methods are available for the detection and measurement of various gas species. Semiconductor sensors usually based on tin(IV) oxide (SnO2) are among the best known types of sensors for the detection of dangerous and harmful gases [1,2]. As reported, a degree of sensitivity of these sensors for a particular gas can be obtained by careful control of the sensor operating temperature and by the addition of suitable dopants [3].
