Optical excitation and external photoluminescence quantum efficiency of Eu(3+) in GaN
We investigate photoluminescence of Eu-related emission in a GaN host consisting of thin layers grown by organometallic vapor-phase epitaxy. By comparing it with a reference sample of Eu-doped Y(2)O(3), we find that the fraction of Eu(3+) ions that can emit light upon optical excitation is of the or...
