Abstract


The phosphates Ca9–xPbxDy(PO4)7 were obtained by standard solid state reaction found to be isotypic with whitlockite-type -Ca3(PO4)2 (polar space group R3c). The introduction of one or several doped cations preserves the structure and creates multi-colored and tunable phosphors. The luminescence properties are discussed. The Ca9–xPbxDy(PO4)7 phosphates shows green result emission and can be used as a potential materials for LED devises.
