Complex spectrum of exciton-impurity complexes in imperfect crystals of tin dioxide
Agekyan V.T.
Luminescence spectra of free and localized excitons in Sn02 were obtained. A phonon-free spectrum has a complex structure whose properties indicate that the excitons are localized on the interacting defects. A significant variation of the energy of the longitudinal optical phonons, which interact with the localized excitons, was detected.
