摘要	Luminescent properties of Eu2+-doped phosphors with nominal composition of 2SrO center dot MgO center dot xSiO(2) (0.8 <= x <= 1.2) are studied. The emission spectra consist of a blue band (460 nm) and a yellow band (550 nm), the relative intensities of which change with the SiO2 composition x. It is found that a combination of the blue and yellow bands can generate white light at x around 1 undernear- ultraviolet excitation. X-ray diffraction patterns of the phosphors demonstrate both Sr3MgSi2O8 and Sr2SiO4 phases, in which Eu2+ contributes to the blue and yellow emissions, respectively. The relative intensity variation of the two bands is attributed to the relative proportion of the two phases dependent on SiO2 composition. A white light emitting diode fabricated using a GaN chip (lambda(em) = 400 nm) and this phosphor is obtained. exhibiting color coordinates of x = 0.33, y = 0.34, color rendering index of 85 and luminous efficiency of 6 lm/W.
