Abstract
Dicke superradiance (DSR) is observed in a molecular mixed crystal, by phenyl with pyrene (wavelength: 373.9 nm; T = 1.5-4.2 K). Characterist ics of DSR under broadband and narrow-band excitations are studied. Th e influence of phonons on the DSR appearance is investigated and the p seudo-localized phonon parameters are established. Two-frequencies DSR and superradiance within a cavity are also observed. The possibility of DSR observation in the gamma range is analyzed.
