Abstract

Abstract: In this work, investigation of the spectroscopic parameters of the luminescence of Yb 3+ ions in single crystalline films of Lu3 Al5 O12 and Y3 Al5 O12 garnets was performed using the synchrotron radiation excitation with the energy in the range of Yb 3+ charge transitions (CT), exciton range and the onset of interband transitions of these garnets. The basic spectroscopic parameters of the Yb 3+ CT luminescence in LuAG and YAG hosts were determined and summarized with taking into account the differences in the band gap structure of these garnets. Highlights: Single crystalline films of Yb doped LuAG and YAG garnets were grown by LPE method. Yb 3+ luminescence of LuAG:Yb and YAG:Yb film were studied using synchrotron radiation. Basic parameters of Yb 3+ charge transfer luminescence in LuAG and YAG were determined.
