Abstract

Optically induced ESR and absorption due to localized paramagnetic states in the forbidden gap have been observed in several semiconducting chalcogenide glasses below ∼15 K. Analysis of the ESR spectra indicates that these centers are holes localized on chalcogens and are not directly associated with impurities.
