Abstract

The effect of60Co irradiation (1-250 Gy) on the optical properties of selected phosphate and silicate-based scintillating glasses was investigated by transmission measurements performed at room temperature in the UV-Visible part of the spectra. Samples doped with rare-earth ions (Ce3+, Tb3+as emission centres, and Gd3+as an additional constituent in certain compositions) have been studied. The results are discussed taking into account the possible influence of different glass compositions on radiation induced colour centres. © 2001 Elsevier Science B.V. All rights reserved.
