Abstract

Sr~2~LiSiO~4~F:Ce^3+^,Li^+^ phosphors have been synthesized by solid‐state reaction. The photoluminescence (PL) emission and excitation behavior of blue‐emitting Sr~2~LiSiO~4~F:Ce^3+^,Li^+^ phosphors have been reported. Three dominant bands centered at about 250, 280, and 340 nm characterized the excitation spectra, which are consistent with the diffuse reflection spectra. Under the excitation of different UV light, the peak of the emission spectrum shifts. The PL excitation spectra monitored by different emission wavelength, the PL excitation spectra of different dopant concentration, and the optimum dopant content have been studied in detail.
