The (Y0.99Nd0.01)3Al5 O12 nano-sized powders were synthesized by low temperature combustion (LCS), using Nd2O3, Y2O3, Al(NO3) 3♦9H2O, ammonia water and citric acid as starting materials. This method effectively solves the problems caused by solid-state reaction at high temperature and hard agglomerates brought by chemical precipitation method. The powders were characterized by TG-DTA, XRD, TEM respectively. The study focused on the photoluminescence (PL) spectra of (Y0.99Nd0.01)3Al5 O12 ceramic green and sintered disks. The experiments show that the forming temperature of YAG crystal phase is 850°C and YAP crystal phase appearing during the calcinations transforms to pure YAG at 1050°C. The particle size of the powders synthesized by the LCS is in range 20-50nm depending on the thermal treatment. The effectively induced cross section (σin) with the value 4.03×10-19cm2 of (Y0.99Nd0.01)3Al5 O12 ceramics is about 44% higher than that of single crystal.
