Abstract

Abstract Depending on the gas concentration of NO 2, the electric and non-electric characteristics of lead phthalocyanine gas sensors change reversibly or irreversibly. These processes have been investigated by IR spectroscopy and XPS to characterize the reasons for the irreversible response and to discuss the lifetime of the sensors.
