Abstract:
Y2.985-xCe0.015CaxAl5-xSixO12 (YAG:1.5%Ce+xCS) ceramic phosphors (CPs) were synthesized by a vacuum sintering method. The addition of CaCO3 and SiO2 significantly reduces the sintering temperature of CPs. The effects of Ca2+ - Si4+ on luminescent properties and microstructures of YAG:Ce CPs are discussed. The Ca2+ - Si4+ cannot be completely dissolved in the YAG:Ce CPs when x reaches to 0.2. Combining the results of XRD, photoluminescence, and cathodoluminescence spectra proved the existence of the Ca2Al2SiO7. The performances of the titled CPs in high-power white laser diodes lighting are characterized.
