Divalent europium (Eu2+)-doped alkaline-earth apatites M5(PO4)3Cl (M = Ca, Sr, Ba) are prepared by wet chemical synthesis method. Formation of Ca5(PO4)3Cl and Sr5(PO4)3Cl is confirmed by X-ray diffraction. Prepared phosphors are analyzed for photoluminescence spectrum. Photoluminescence emission spectrum for Ca4.95(PO4)3Cl:0.05Eu2+ and for Sr4.95(PO4)3Cl:0.05Eu2+ shows bands centered at 449 nm and...
