| 英文摘要 | a series of eu2+, mn2+-doped na3lusi2o7 (nlso) phosphors have been prepared via the high-temperature solid-state reaction route. x-ray diffraction (xrd), raman and fourier transform infrared (ft-ir) spectra, fluorescent decay times, photoluminescence (pl) including temperature-dependent pl properties and scanning electron microscopy (sem) were used to characterize the as-prepared samples. in eu2+ singly-doped nlso samples, an intense green emission is presented under uv excitation. a tunable color from green to yellowish-orange was generated when mn2+ ions were co-doped into the nlso: eu2+, which is based on the energy transfer from eu2+ to mn2+ ions. the energy transfer from eu2+ to mn2+ ions can be speculated to be due to the wide spectral overlap between the eu2+ emission and mn2+ excitation spectra in eu2+ or mn2+ singly-doped nlso samples. this is demonstrated by the similar excitation spectra of the eu2+ and mn2+ emission bands and the decreases in eu2+ emission intensity and decay lifetime with the increase of mn2+ concentration in the nlso: eu2+, mn2+ samples. the energy transfer mechanism from eu2+ to mn2+ ions was determined to be a dipole-quadrupole interaction by the concentration quenching and spectral overlap methods. the maximum quantum yield can reach 51.5% for nlso: 0.01eu(2+), 0.12mn(2+). the above results indicate that nlso: eu2+, mn2+ could be a candidate as a green to yellowish-orange component for uv-excited w-leds. |
