| Abstract;Radiation-induced luminescence phenomena from natural minerals, involving after-glow (AG) and thermoluminescence (TL), should be concerned with trapped electrons and positive holes as luminescence centers associated with impurities and/or lattice defects. When these feldspars were subjected to thermal treatments beyond 700 .DEG.C., an electron spin resonance (ESR) spectrometry showed existence of two kinds of hydrogen radicals, which were trapped in different sites at the liquid nitrogen temperature. Newly created hydrogen radicals existed even in room temperature and operated as killer of luminescence centers. (author abst.) |
