Abstract
- Abstract: In this paper, some results on visible luminescence performed on Yb3+-doped gadolinium gallium garnets under 165 and 940nm excitation were presented. The upconversion luminescence was ascribed to Yb3+ cooperative luminescence and the presence of rare earth impurity ions. The gain cross-sections of Yb:GGG crystal as a function of excited-state population fraction β were studied. Emission spectra under 165nm at 20K showed there was no charge transfer luminescence in Yb:GGG. [Copyright &y& Elsevier]
