Abstract

A combustion synthesis method has been developed for synthesis of Eu2+ doped CaAlSiN3:Eu2+ phosphor and its photoluminescence properties were investigated. Ca, Al, Si, and Eu2O3 powders were used as the Ca, Al, Si, and Eu sources. NaN3 and NH4Cl were found necessary to be added for the formation of the product phase and addition of Si3N4 was found to enhance the product yield. These powders were mixed and pressed into a compact which was then wrapped up with an igniting agent (Mg+Fe3O4). The reactant compact was ignited by electrical heating under a N2 pressure of 0.8 MPa. The synthesized CaAlSiN3:Eu2+ phosphor absorbs light in the region of 240-520 nm and shows a broad band emission in the region of 500-800 nm due to the 4f65d1→4f7 transition of Eu2+. The synthesized phosphor thus has a potential application as a red phosphor for white LED lighting.
