Abstract

ESR observations of aluminum-doped paratellurite (α-TeO2:Al) single crystals after electron irradiation near room temperature indicate four radiation-induced electron-like defects with similarities to the intrinsic Vo. center, which is also present. From measurements of angular variations and tellurium hyperfine interactions it is evident that the four centers represent a family of Vo. centers perturbed by Al3+; that is, VoAlTex centers. The new centers are detected only in Al-doped crystals; however, the aluminum impurity ions appear to be too far from the Vo. to yield 27Al hyperfine interaction measurable by ESR.
