利用传统高温固相法合成了一种新颖的绿色荧光粉Ba9 Lu2 Si6 O24∶Eu2+。通过X-射线粉末衍射仪(XRD)对已得荧光粉样品进行了结构表征；通过扫描电子显微镜(SEM)观察了样品的形貌；利用激发、发射谱系统地研究了样品的荧光特性。结果表明：样品在紫外-蓝光(250~480 nm)区域有很好的吸收，并在375 nm激发下，得到505 nm处明显的宽绿光发射带。这些结果说明：Ba9 Lu2 Si6 O24∶Eu2+荧光粉是一种很有应用前景的白光LED用绿色荧光粉。

A novel green-emitting Ba9 Lu2 Si6 O24∶Eu2+ phosphor was synthesized by conventional solid-state re-action method. The phase formation of as-prepared samples were investigated by X-ray diffraction ( XRD) . The particle morphology was determined by scanning electron microscope ( SEM) . Photoluminescence excita-tion and emission spectra indicated that the phosphor could be eficiently excited by UV-blue light (250~480 nm), and presented broad green emission. The result indicated that Ba9Lu2Si6O24∶Eu2+ would be a promising green-emitting phosphor for white LEDs.
