Exciton Luminescence and Optical Properties of Nanocrystalline Cubic Y₂O₃ Films Prepared by Reactive Magnetron Sputtering.

ABSTRACT: This paper presents a comprehensive study of the energy structure, optical characteristics, and spectral-kinetic parameters of elementary excitations in a high-purity nanocrystalline cubic Y₂O₃ film synthesized by reactive magnetron sputtering. The optical transparency gaps for direct and indirect interband transitions were determined and discussed. The dispersion of the refractive index was established based on the analysis of interference effects. It was found that the refractive index of the Y₂O₃ film synthesized in this study is higher in order of magnitude than that of the films obtained with the help of other technologies. The intrinsic emission of Y₂O₃ film has been discussed and associated with the triplet-singlet ra
