In Gd2O3 nanoparticles doped with Er3+ ions at 0.25-8 mol percent concentration, the properties of electron transitions in the region of fundamental absorption edge, as well as vibrational characteristics, are examined. For cases of direct and indirect interband transitions, initial reflection data is analysed. The related energy gaps are shown to be dependent on activator concentration. The effect of a large decrease in phonon frequency when a matrix is doped with a modest amount of Er3+ is discovered. The information acquired opens up new avenues for increasing the efficiency of energy conversion devices. The results show that there is a possibility of reducing thermal losses during the radiation conversion.
