ESR Studies on the stability of trapped electrons in photoionized and gamma-irradiated organic glasses

Abstract

Trapped electrons have been detected by electron spin resonance following phcioionization and gamma-irradiation experiments with several organic glasses at 77°K. The results show that for each glassy material, the trapped electron has a characteristic thermal stability which is unaffected by the method of generation. It is concluded that in these systems, the mobility of the trapped electron is the decisive factor- in controlling the rate of thermal decay. The electron mobility in 3-methylpentane appears to be strongly influenced by the presence of polar molecules (amines) in the environment.
