The results of a study of charge transfer luminescence (CTL) in a YAG:Yb monocrystal and trans-parent ceramics obtained by vacuum sintering and nanocrystalline (VSN) technology from a weakly agglomerated powder are presented. The kinetics of CTL decay at temperatures of 8, 100, and 300 K and different excitations were obtained. The results of the measurements are analyzed from the viewpoint of comparison of monocrystal and ceramics properties. The high quality of the latter is demonstrated.
