通过在Sr2SiO4∶Eu2+荧光粉中加入MgO,提高了Sr2SiO4∶Eu2+荧光粉的蓝光和黄光发射带的发射强度,研究了MgO浓度对Sr2SiO4∶Eu2+荧光粉发光强度的影响.当Mg与Si的量比在1.0附近时,荧光粉的亮度较高,且发光颜色为白色.通过调节Sr2SiO4∶yEu2+,MgO荧光粉中Eu2+的掺杂浓度,可以调节荧光粉的发光颜色.用Sr2SiO4∶Eu2+,MgO和400nm的InGaN管芯制备的白光LED,色坐标优于α′Sr2SiO4∶Eu2+和βSr2SiO4∶Eu2+荧光粉制成的白光LED,显色指数和流明效率高于βSr2SiO4∶Eu2+和α′Sr2SiO4∶Eu2+制成的白光LED
