The mechanisms of formation of the spectra of interband optical absorption in nanosystems containing aluminum oxide quantum dots, placed in the matrix of vacuum oil, are presented. It is shown that the electron transitions in the band of the electron–hole pair states cause absorption in the ultraviolet wavelengths and cause the experimentally observed significant blurring of the absorption band.
