400-NM Photoluminescence of a Color Center in Undoped YAG Grown under Reducing Atmosphere

摘要

We describe a color center in reduced YAG (yttrium aluminium garnet) which luminesces in a broad band centered around 400 nm with high quantum efficiency, 4 ns radiative lifetime, and comparatively small Stokes shift. 13 refs., 2 figs. (ERA citation 13:006057)
