摘要：

Evidence is presented that erbium will occupy one of two sites in phospho-aluminosilicate glass dependent on the Al:P ratio. Although high energy P=O vibrational modes are created we suggest these are localised and only couple to one type of Er site. Decay rates and Er-Yb amplifier performance are then critically determined by the Al:P ratio.
