Abstract
Optical and optoelectronic properties of Pb5CrO8 thin films prepared by an electron-beam evaporation deposition technique are described. The relation between spectral response of Pb5CrO8 thin-film lateral photodetectors and annealing temperature for developing the crystallization of the films is examined. An obtained spectral response for adequate annealing temperature covers an entire visible region. A large ratio of photocurrent and dark current and a fast response characterize the thin-film photodetector. An application to a color contact-type line-image sensor is also discussed to demonstrate the optoelectronic ability of the lateral Pb5CrO8 thin film.
