Abstract
Based on the temperature dependence of the fundamental absorption edge of thin PbWO4 films, we studied the exciton–phonon interaction, which made it possible to interpret the absorption edge as the absorption of autolocalized excitons. The temperature dependence of the forbidden band gap is investigated.
