Luminescence in LaCaAl3O7 prepared by combustion synthesis

LaCaAl3O7 phosphors activated by several ns2 impurities like Pb2+ and Bi3+, and rare-earth dopants were prepared by combustion synthesis. X-ray diffraction (XRD) results confirmed the formation of single-phase compounds. Variety of activators exhibited interesting photoluminescence in LaCaAl3O7 host. Combustion synthesis furnishes a quick method for preparing these phosphors. It is suggested that LaCaAl3O7-based materials can be developed as low-cost phosphors.
