Paramagnetic defects in $\gamma$- irradiated, pure and doped (with As, Cl and Br) selenium

Özet

This paper presents results of an EPR spectrum investigation of $\gamma$-irradiated ($Co^{60}$ dose $10^7$Rad) glasses Se, $SeCl_x$, $Se_{0.95}As_{0.05}Cl_x$ and $Se_{0.95}As_{0.05}Br_x$ (x=0.001-0.1) at 77 K. An analysis of spectra reveals that two types of paramagnetic radiation-induced defects arise (broken bonds localized on Se and As atoms) from the irradiation of such chalcogenide glasses.
