Abstract

The optical properties of rare earth ions in solids have been of interest for many years. However, the luminescence properties of 4f ions in III–V semiconductors and silicon have remained unexplored, despite their obvious potential for light emitting and laser diodes. The characteristic photoluminescence and electroluminescence spectra of rare earth ions in III–V and silicon semiconductors were reported recently [1–4].KeywordsExcitation FunctionLuminescence CenterElectron Energy Distribution FunctionImpact ExcitationTransition Metal ImpurityThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
