Optical and Thermal Bleaching of Trapped Electrons in Aliphatic Amine Glasses

Abstract

An optical bleaching study has been made of trapped electrons in γ-irradiated aliphatic amines at −196 °C. The results indicate that the optical absorption of the trapped electrons in the amines is attributed to optical transitions to both bound excited states and a continuum state. The thermal decay of the trapped electrons has been studied by the e.s.r. technique at temperatures above −196 °C. It has been found that the line width of the e.s.r. spectra of the trapped electrons in some of the amines changes on warming.
