Abstract

The magnetic circular dichroism of the optical absorption (MCDA) and optically detected ESR of CaO·P₂O₅ and CaO·P₂O₅-Tb₂O₃ glasses X-irradiated at RT are investigated. For the first time a direct correlation is obtained between the ESR spectra and magneto-optical absorption bands of radiation-induced defects in phosphate glasses. It is found that both PO₄^2- and PO₃^2- centers have several strongly overlapping absorption bands in the visible and infrared spectral regions. In Tb³⁺-doped CaO·P₂O₅ glass an intense derivative-like MCDA signal around 3.25 eV is assigned to the hole center Tb⁴⁺.
