Abstract

This is the first report of ESR observations of three distinct paramagnetic centers in TeO2 glasses. One center is intrinsic to the glass and the other two are induced by KrF-excimer-laser radiation. The intrinsic center with a broad ESR spectrum is tentatively identified as an oxygen-associated hole center. One radiation-induced center fades slowly at room temperature; its proposed structure is that of an electron trapped in a diffuse orbital associated with a modifier ion. The other radiation-induced center is stable at room temperature and corresponds to the Vo. center observed in crystalline paratellurite.
