The effect of annealing on Some Optical characteristics of (CdO:Ag2O) films prepared by spray pyrolysis

Abstract

Thin films of (CdO:Ag2O) were deposited on glass substrates by spray pyrolysis and annealed in air at 450 ºC. Some optical properties of the thin films were studied after and before annealing. After annealing both transmittance% , Skin depth and optical energy gap increased but localized states and carrier concentrations decreased after heat treatment.
