Photoluminescence Properties of Eu3+ and Ce3+ Activated Calcium Chlorophosphate Via Combustion Synthesis Method

Calcium chlorophosphate (Ca2PO4Cl) phosphors, activated by rare earth ions Eu 3+ and Ce3+ were prepared by urea assisted combustion synthesis technique and their characterization and luminescent properties were studied. The synthesized phosphors were investigated by powdered XRD, SEM and Photoluminescence characterization (PL) methods. PL excitation spectra of Ca2PO4Cl:Eu 3+/Ce3+ phosphor exhibit narrow bands in the near ultra violet (n-UV) range, and the PL emission spectra of Ca2PO4Cl: Eu3+/ Ce3+ phosphor shows sharp narrow bands typical of rare earth ions. The bands observed in the PL emission and excitation spectra of Ca2PO4Cl: Eu 3+/Ce3+ phosphors can be ascribed to the electronic transitions within 4f configurations of rare earth ions. The excitation peaks for Ca2PO4Cl: Eu 3+ is in n-UV range. The obtained results suggest that these phosphors may be favorable for lamp industry.
