Interference effects in the UV(VUV)-excited luminescence spectroscopy of thin dielectric films

Abstract

The problem of exciting UV and VUV light interference affecting experimental photoluminescence excitation spectra is analysed for the case of thin transparent films containing arbitrarily distributed emission centres. A numerical technique and supplied software aimed at modelling the phenomenon and correcting the distorted spectra are proposed. Successful restoration results of the experimental synchrotron data for ion-implanted silica films show that the suggested method has high potential. © 2013 International Union of Crystallography Printed in Singapore-all rights reserved.
