The influence of calcium oxide on the 60Co-γ ray irradiation resistance of Ce-doped (alumino-) borosilicate glass

Irradiation-induced UV–VIS absorptance spectra and electron paramagnetic resonance X-band spectra of some cerium (Ce)-doped borosilicate glasses and alumino-borosilicate glasses were studied, and it was found that the addition of calcium oxide could reduce irradiation resistance of Ce-doped (alumino-)borosilicate glass. As a result, the concentration of calcium oxide in the Ce-doped irradiation-resistant (alumino-)borosilicate glass should be reduced.
