Abstract

RRUFF database is proposing the Raman broad scans of glasses CaO-Al2O3-SiO2 with rare earth element (REE) oxides, that is of CaO-RE2O3-Al2O3-SiO2 glasses. Raman data are courtesy of E. Cairns, University of Edinburgh. Here we show how we can use the q-BWF functions to decompose these spectra. The q-BWF functions are generalizing the Breit-Wigner-Fano line shape in the framework of the q-exponential function proposed by Constantino Tsallis and his statistics. Besides asymmetry, the decompositions with q-BWF line shapes are stressing Gaussian and non-Gaussian behaviors of components. The data analysis of CaO-RE2O3-Al2O3-SiO2 glasses is highlighting the presence of photoluminescence regular patterns in the Raman broad scans. In another database, the Raman Open Database (ROD), we can find some spectra of rare-earth oxides. Therefore, it is possible to compare the available REO spectra with those of CaO-RE2O3-Al2O3-SiO2 glasses and study the broadening of the Raman bands.
