摘　　要：采用高温固相法,合成了Eu2+掺杂的Sr2B5O9Cl系列蓝色荧光粉,并对其发光性质进行研究.结果表明:该荧光粉在紫外区域显示出较强的宽带激发,当Eu2+的掺杂质量分数为4%时,Sr1.96B5O9Cl∶0.04Eu2+的发光强度最大,色坐标为(x=0.161,y=0.019).To obtain new blue phosphors, a serial of phosphors Sr2B5O9Cl doped with different Eu2＋ concentrations were prepared with the solid - state reaction technique, These phosphors show some intense blue emission with and their photolumineseent properties were investigated. some broad excitation in UV range. The emission of the phosphor Sr1.96B5O9Cl：0.04Eu^2＋ has the optimum blue emission, with good CIE （Commission Internationale de 1 Eclairage, International Commission on Illumination） chromaticity coordinates x = 0. 161, y = 0. 019.
