Abstract
It was found that thin films evaporated onto a substrate in vacuum exhibit both thermoluminescence (TL) and thermally stimulated exoelectron emission (TSEE) when they are heated without any stimulative pre-treatment. These phenomena were observed only once after evaporation, and succeeding repeated heating showed neither TL nor TSEE. The heating rates used were 0.5°C/s for TL and 1°C/s for TSEE. In this study, the temperature at the main glow peak of TL or TSEE from the unirradiated films was found to be higher than that from these irradiated with gamma-rays.
