Features of XEOL spectra evaluation depending on optical density of the sample

Abstract

Effect of competition in excitation between luminescence centres and the rest of a sample on intensity of luminescence in the visual range under exciting with synchrotron radiation is considered. It is shown that the competition gives rise to distortion of XEOL spectra. In this case the obtained structure data are incorrect. An algorithm of data correction is proposed. It is demonstrated that, to apply this algorithm, it is necessary to use three-detector circuit of recording XEOL spectra. The examples of correction of XEOL spectra of KBr and NaCl-Ni samples are given.
