Abstract
Codoping AlxGa1−xAs with both erbium and oxygen drastically enhanced the intensity of the Er3+‐4f emissions over that observed from AlxGa1−xAs doped with Er alone, however, similar codoping in GaAs did not result in any enhancement. It is believed that the enhancement of the intra‐4f emissions is either due to the formation of Er‐Al‐O complexes or Er‐O complexes along with the variation of the band gap in AlxGa1−xAs, or both.Keywords
