Abstract
Photothermal spectroscopy using thermistor is applied to study the heat generation of sputtered ZnO thin film together with the optical absorption character. It shows that the increase of signal intensity of heat generation is different from that of optical absorption. The width of the exponential changes for the total rate of optical energy absorption is larger than that of the heat generation just below the fundamental absorption edge.
