The work is devoted to an analysis of the formation processes of radiation
displacement defects (RDDs) and color centers (CCs) under irradiation of co
mplex oxide crystals. The results of the displacement process simulation as
well as the analysis of the RDDs and CCs accumulation kinetics in some com
plex oxide crystals are presented. New experimental results on additional a
bsorption spectra induced by neutron irradiation of LiNbO3 (LNO) crystals d
oped with Fe and Cr and YAlO3 (YAP) crystals doped with Nd and Er as well a
re presented. Dose dependencies are compared and their peculiarities are di
scussed. (C) 2000 Elsevier Science B.V. All rights reserved.
