[Determination of Eu in long-afterglow of the SrAl2O4:Eu2+, Dy3+ phospher samples by LMESA].
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.
