摘要
Double-quantum photoelectron emission from perylene and naphthacene crystal has been studied. Action spectra and time Profiles of the photoemission indicate that, below 3.2 eV, photoemission occurs by fusion of two singlet excitons in perylene and by photoionization of singlet exciton in naphthacene. Above 3.2 eV it seems probable that conduction electrons are being photoemitted.
