Multivariate analysis as a tool for Ion Beam Induced Luminescence (IBIL) spectra interpretation.

Multivariate analysis is used to identify the number and wavelength position of components evolving during irradiation with different rates in Ion Beam Induced Luminescence (IBIL) spectra. The method, based on the study of the eigenvectors of the matrix whose elements are the luminescence intensity values for different wavelengths and fluences, is tested on two different simulated cases and on experimental IBIL spectra collected from a polysiloxane scintillators.
