Abstract
Transparent conducting zinc oxide (unintentionally doped) films were prepared by spray pyrolysis using air as the carrier gas. The optical and electrical properties of the films are presented and discussed as a function of the substrate temperature. The optical properties were studied in the ultraviolet (u.v.) visible and near infrared (i.r.) regions. The transmittance data were used to determine the optical constants, the refractive index, n, the extinction coefficient, k, and the absorption coefficient, α. The reflectivity of the films was calculated and found to be very small in the wavelengths investigated, showing a tendency to increase in the i.r. range in order to act as a host reflector.
