Abstract

Radiation induced absorption spectra (irradiation up to 500 Gy by60Co) and TSL of a set of YAP:Ce crystals co-doped by Zr4+were investigated. Positive effect of Zr4+co-doping was found, namely reduction of both the defect creation and presence of TSL active traps. Up to three absorption bands were observed in the radiation induced absorption spectra. They probably have different origin - from colour centers in the green part of the spectra to change of the Ce3+valency in the near UV.
