Abstract
A series of Ba2Ca(PO4)4:Dy3+ phosphors were synthesized by the wet chemical method and the photoluminescence properties were systematically investigated. Under the 350 nm near ultraviolet excitation, Ba2Ca(PO4)4:Dy3+ phosphor shows emission peak at 475 nm (blue) and 572 nm (yellow). At 0.5 mol% of Dy3+ ions, concentration quenching was shown. The present study implies that the Ba2Ca(PO4)4:Dy3+ phosphors would be a suitable choice for solid-state lighting applications as a near ultraviolet convertible phosphor.
