Phase behavior is studied in erbium‐doped Y 3 Al 5 O 12 (YAG) garnets synthesized by solid‐state reactions. High resolution synchrotron XRD and SEM‐EDX studies reveal phase separation at an erbium content between 8 and 50 at%, depending upon the processing conditions. Similar results are found in closely‐related garnet systems. The phase separation has a striking effect on the optical properties of YAG:Er 3+ .
