Abstract
Films of palladium oxide of good optical quality have been prepared by the oxidation of sputtered films of palladium. Optical absorption and photoconductivity measurements indicate extrapolated band gaps of 2.13±0.03 eV and 2.67±0.03 eV respectively with the photoconductivity showing an exponential tail extending to lower energies. Measurements of the thermal stability of the films in the presence of a low partial pressure of oxygen indicate a dissociation enthalpy of −1.17±0.06 eV. The presence of hydrogen in the ambient during decomposition was found to reduce the temperature for decomposition to palladium metal from about 580 to 350 K.
