Abstract

Up to 40% substitution of scandium for aluminum in YAG ceramics has been achieved, and the transparent Nd-doped Y 3 Sc x Al ( 5 x ) O 12 ( Nd : YSAG ) ceramics were successfully fabricated by sintering nanosized powder compacts under H 2 atmosphere. It was found that 40% scandium substitution for aluminum can significantly enhance the light-emission intensity around 1064 nm of the Nd : YSAG ceramics by 2–3 times as compared with Nd : YAG single crystal without Sc 2 O 3 doping when pumped with the same 808 nm diode laser. In addition, the material was found to have prolonged fluorescence lifetime.
