Description

Intrinsic emission of complex oxides with garnet structure was studied by means of the analyses of the time-resolved luminescence spectra and decay kinetic for single crystals (SC) and single-crystalline films (SCF) of Y3Al5O12 (YAG) and Lu3Al5O12 (LuAG) garnets under excitation by the pulse X-ray and synchrotron radiation at 8-300 K. YAG and LuAG SC and SCF are characterized by significantly different concentration of the YAl and LuAl antisite defects (AD) due to the substantial difference in the conditions of their crystallization. For this reason, LuAG and YAG SC and SCF are very useful model objects for the study of nature of the intrinsic emission of these oxides, consisting of the excitons and AD luminescence.
