| 摘 要： | 激光微区发射光谱分析法结合CCD光学多道分析仪测定了SrAl2O4:Eu2 ,Dy3 长余辉材料中铕的含量,研究了该方法用于长余辉材料定量分析的准确性。实验中以Eu(Ⅱ)412.973nm为分析线,计算机拟合LogIf~Logc工作曲线,对Eu的分析结果表明:分析谱线相对强度RSD为4.3%,定量分析相对标准偏差RSD为7.4%,分析结果的平均值为2.13%;采用高温固相反应法制备SrAl2O4:Eu2 ,Dy3 长余辉材料,制备前后的Eu百分含量发生明显变化,高温合成后的长余辉材料中Eu百分含量明显增大。

| Abstract: | A method for the determination of Eu in Long-aferglow of the SrAl2O4:Eu2+, Dy3+ phospher samples by laser microemission spectral analysis was developed. And the accuracy of this method was studied. Analyses of Eu in Long-aferglow of the SrA1204: Eu2+, Dy3+ phospher samples, using the Eu (11) line at 412.973 nm, show that RSD of relative intensity of spectral lines is 4.3%, RSD of quantitative analysis is 7.4%, the average of quantitative analysis is 2.13%. Compared with the content before samples synthesized, it can be concluded that the content of Eu in the SrAl2O4:Eu2+, Dy3+ phospher samples synthesized by high temperature solid phase reaction has an obvious increase. |
