Luminescence spectra(4.2 K) and etch patterns of thermally deformed anthraccnc single crystals are investigated. It is shown that the Dt band with AE = 235 cm-t (where AE is the energy gap between the bottom of the exciton band and the DI band) is due to the edge dislocations with the emergences at
