Abstract
Photoinduced IR absorption measurements are reported On WO3. A photoinduced midinfrared small polaron peak centered at 4800 cm(-1) (0.59 eV) was obser ved. The data were analyzed in the framework of the photon-assisted small-p olaron hopping theory and briefly compared to previously published infrared absorption measurements in WO3 and photoinduced IR absorption measurements in high T-c cuprates.
