Trapped Electrons in Irradiated Quartz and Silica: I, Optical Absorption

Abstract

Evidence is given for the correlation between an optical absorption band at 2300 a.u. and an electron spin resonance system developed in quartz after 60 Co γ‐irradiation. The results of bleaching γ‐irradiated quartz and silica at 78°K. and at room temperature are presented and discussed. Also, further observations upon annealing these color centers are given.
