Abstract

The blue-emitting phosphors of Eu2+ doped Ca10(PO4)6Cl2 were prepared by combustion synthesis, characterized by X-ray powder diffraction measurement, SEM (Scanning electron microscopy) and Photoluminescence (PL) techniques, has been reported. The luminescence properties were investigated by photoluminescence excitation and emission spectra. The phosphor exhibited the blue luminescence due to the 4f6 5d1 → 4f7 transition of Eu2+ ions under the excitation of near UV light. PL emission spectrum of Eu2+ ion under 353 nm excitation gives PL emission at 456 nm (Blue) due to 4f6 5d transitions. The concentration quenching of Eu2+ ions in the Ca10(PO4)6Cl2 host is determined to be 0.5 mole % , demonstrating CIE chromaticity coordinates of (0.149,0.023). The above results suggest that the Ca10(PO4)6Cl2:Eu2+ phosphor is a promising blue-emitting phosphor for application in near-UV white light-emitting diodes.
