description: The given work is devoted to the study of the processes of upconversion in thin films of Y2O3, as well as the epitaxial growth of these structures. The aim of the work was to study the effect of various substrates and concentrations of impurities on luminescent properties. Tasks to be solved during the research:Â Creation of new Y2O3 thin film structures using laser molecular beam epitaxy.Â Carrying out complex experiments on optical spectroscopy aimed at obtaining upconversion spectra. Analysis of the obtained data. Laser molecular beam epitaxy technology was used to growth samples, standard optical spectroscopy methods were used to study luminescence spectra. As a result of the experiments carried out, it was found that thin films of Y2O3 grown on strontium titanate substrates with concentrations of doping Er3+ ions 5% and Yb3+ 22% are the best from the point of view of optical upconversion. The results of this work will be used in further studies of optical upconversion during the growth of superlattices.
