摘要：

Optical absorption and paramagnetic resonance spectra of X-ray irradiated (lambda(CuKalpha), = 0.154 nm) ultra- and metaphosphate glasses of high purity were studied. Melting of the samples under different redox conditions, investigation of annealing behavior of the irradiated samples and correlation between optical and EPR spectra allowed the resolution of five main paramagnetic radiation-induced defects and associated optical absorption bands. Phosphorus and oxygen related radiation-induced defects were found, with hole centers POHC and OHC absorbing in the visible and electron trapped centers PO2, PO3 and PO4 absorbing in the ultraviolet region.
