英文摘要	eu2+-doped srsi2o2n2 has recently been identified as a viable green phosphor that in conjunction with a blue-emitting diode can be used in solid-state white-lighting sources. in this study, we attempt to improve the photoluminescence and thermal quenching behavior by codoping re3+ (re = la, gd, y, dy, lu, sc) and li+ instead of sr2+. trivalent cation substitution at the sr2+ site enhances the photoluminescence intensities and also achieves better thermal stability at high temperature. the lifetime decay properties in the related substituted phosphors are investigated. furthermore, under the 460 nm blue light irradiation, this green phosphor exhibits excellent luminescence properties with absorption and internal/external efficiencies. high-color-rendition warm-white leds using the phosphor have the color temperature and color rendition of 4732 k and 91.2, respectively, validating its suitability for use in solid-state white lighting.
