Eu2+-activated Sr2LiSiO4F phosphors were synthesized at 900°C by solid-state reaction in reducing atmosphere, and their photoluminescence (PL) properties were systematically investigated by diffuse reflection spectra, PL excitation and emission spectra, and by the fluorescence decay curve. Sr2LiSiO4F:Eu2+ emits intense green light at 520 nm originating from the 5d14f 6-4f7 transition of Eu2+ under 365 nm n-UV excitation. The PL excitation spectrum matches the emission from n-UV chips. These materials could be promising green phosphors for use ...
