摘要：

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.
