Effects of palladium on the optical and hydrogen sensing characteristics of Pd-doped ZnO nanoparticles

Abstract

The effect of palladium doping of zinc oxide nanoparticles on the photoluminescence (PL) properties and hydrogen sensing characteristics of gas sensors is investigated. The PL intensity shows that the carrier dynamics coincides with the buildup of the Pd-related green emission. The comparison between the deep level emission and the gas sensing response… (More)
