Abstract: | This report is devoted to the study of the low and room temperature photoluminescence and photoacoustic spectroscopy of the Fe3+ impurity ion in the LiGa5O8–LiGaSiO4–Li5GaSi2O8 system. The sample was obtained by solid-state reaction between β-Ga2O3, Li2CO3, SiO2 and appropriated quantities of Fe2O3. It was investigated by X-ray diffraction to determine the formed phases and through photoluminescence, excitation and photoacoustic spectroscopy measurements. The broad absorption and emission bands in the visible and near-infrared spectral regions presented by that system constitute the motivation for this study. More specifically, the luminescence occurs over a large interval of wavelengths, between 400 nm and 800 nm. |
