The recorded luminescence spectra clearly exhibit the line-type fine structure. It was shown that this fine structure of spectra reflects the interaction of electron excitations both with local vibrations of nonbridging oxygen atoms and with phonon modes of the glassy network during the radiative relaxation of the triplet state of L-centers. The appearance of additional “mixed” vibrations discussed and interpreted in terms of the expanded model of an L-center.
