| Abstract: | Spectroscopic properties of YAG and YAP doped with Fe were compared. YAG :Fe crystals grown under reducing atmosphere showed strong colouration whereas similar colouration in YAP :Fe was found after oxygen treatment. Nd3+ luminescence was effectively quenched by Fe ions in YAP, whereas Ce3+ luminescence was quenched by Fe ions in both the materials. |
