| Abstract | A series of Eu2+-activated Sr9Sc(PO4)(7) yellowish-green emitting phosphors were synthesized by conventional solid-state reaction. The photoluminescence (PL) properties and concentration quenching mechanism of the as-prepared phosphors were investigated. The emission spectrum exhibits a broad and asymmetric band peaking at 510 nm, which corresponds to the 4f(6)5d(1) -> 4f(7) transition of Eu2+. The excitation spectrum exhibits a broad band extending from 250 to 450 nm, which matches well with the.emission of near ultraviolet (n-UV) chips (350 430 nm). Non-radiative transitions between Eu2+ ions in the Sr9Sc(PO4)(7) host have been demonstrated to be attributable to dipole dipole interactions, and the critical distance was calculated to be 23.1 A. These results indicate that Sr9Sc(PO4)(7):Eu2+ phosphor could serve as a promising candidate for application in n-UV white-light LEDs. (C) 2013 Elsevier Ltd and Techna Group S.r.l.
