Abstract

Low-temperature infrared spectra reveal multicenter nature of the Ce3+ dopant in various Czochralski grown garnets, perovskite crystals, and YAG transparent glass. Some of these multicenters are associated with antisite defects, i.e. rare-earth ions substituting smaller cations in different crystallographic positions. The antisite defects have detrimental effect on the scintillation properties of these materials. The epitaxially-grown from flux layers of these materials contain much smaller amount of these defects due to low temperature of growth.
