Abstract

This work describe the synthesis of a series of Europium ion (Eu2+) activated calcium chlorophosphate Ca2−XPO4Cl:xEu2+, x = 0.01, 0.015, 0.02, 0.05 and 0.10) phosphors annealed at various temperature. This phosphor is synthesized by wet chemical synthesis. This synthesis method is more efficient than conventional solid state synthesis. The formation of crystalline structure of Ca2PO4Cl of the synthesized phosphor is confirmed by X-ray diffraction analysis. The photoluminescence characterization is carried out and optimal Eu2+ concentration is determined as 2 mol.%. The excitation spectra of Ca2PO4Cl:Eu2+ phosphor shows prominent excitation band around 380 nm. Upon excitation at 385 nm, the phosphor emits light in the range 400 nm to 520 nm peaking at 452 nm. The Commission Internationale de I'Eclairage (CIE) chromaticity coordinates of the phosphor are calculated to be Cx = 0.154 and Cy = 0.022. The PL emission of the prepared phosphor is more intense than commercial BaMgAl10O17:Eu2+ BAM phosphor. This phosphor may be a candidate for the application in solid state lighting as blue emitting component.
