N2 - Eu2 activated Ca5(PO4)3Cl blue-emitting phosphors were prepared by the conventional solid state method using CaCl2 as the chlorine source and H3BO3 as flux. The structure and luminescent properties of phosphors depend on the concentrations of Eu2, the amount of CaCl2 and the usage of the H3BO3 flux were investigated systematically. Eu2 and Mn2 Co-doped Ca5(PO4) 3Cl with blue and orange double-band emissions were also researched based on the optimal composition and synthesis conditions. The energy transfer between Eu2 and Mn2 was found in the phosphor Ca 5(PO4)3Cl:Eu2, Mn2, and the Co-doped phosphor can be efficiently excited by near-UV light, indicating that the phoshor is a potentional candidate for n-UV LED used phosphor.
