摘　　要：采用溶胶-凝胶法和高温固相反应法合成了Eu3+掺杂的SrB4O7、SrB2O4、Sr2B2O5、Sr3B2O6荧光体.荧光光谱测试结果表明在不同基质中Eu3+的荧光发射是有区别的,Sr2B2O5:Eu3+、Sr3B2O7:Eu3+发射峰在610nm左右的红光区,SrB2O4:Eu3+的发射峰在593nm的橙色区,而SrB4O7:Eu3+则表现出了Eu2+离子的特征峰,产生这种区别主要是由Eu3+所处的配位环境不同造成的.荧光体SrB4O7:Eu3+、SrB2O4:Eu3+、Sr2B2O5:Eu3+、Sr3B2O6:Eu3+的最佳掺杂浓度为2％左右.Eu3+ doped borate phosphors (SrB4O7, SrB2O4, Sr2B2O5, Sr3B2O6) were prepared by solid state reaction and sol-gel technique, respectively. The luminescent results showed that the four kinds of phosphors have different luminescent properties. The Sr2B2O5:Eu3+, Sr3B2O7:Eu3+ phosphors have the red emission at 610 nm, the SrB2O4:Eu3+ phosphor has the orange emission at 593 nm, however the SrB4O7:Eu3+ phosphor displays the emission peaks of Eu2+ ion, all that result from the different Eu-O coordination environment. The optimal doping concentration of phosphors is 2%.
