Enhancement of the Er3+ emissions from AlGaAs:Er codoped with oxygen

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 ei...
