Abstract
Photothermal measurement using thermistor is applied to study the heat generation by nonradiative processes in erythrosine B dye in epoxy resin. It shows that the incident light intensity dependence of heat generation using an Ar ion laser is nonlinear and corresponds to that for the transmission of erythrosine B in epoxy resin. The increase of the signal intensity of the heat generation is different from that of total rate of optical energy absorption.
