• Abstract:

  Yttrium Aluminum Garnet (YAG) powder doped with rare earth (RE) ions (RE= Ce3+, Eu3+, Nd3+ and Pr3+) were prepared via combustion synthesis at relatively low temperature. The combustion synthesis involves the reaction of aluminum nitrate (Al(NO3)3), yttrium nitrate (Y(NO3)3) and the rare earth ion nitrates (RE(NO3)3) with carbohydrazide (CO(N2H3)2) as fuel. As-synthesized YAG:RE powder samples were amorphous or nano-crystalline however, after annealing at 1000 oC temperature throughout one hour their reached a cubic perovskite type structure. The PL spectra of YAG:RE powders synthesized in this work confirmed the incorporation of RE ions in the YAG host lattice. This research showed that the Combustion Synthesis is a low-cost and rapid method to produce high quality YAG:RE powders.
