- 中文摘要: The dual emission spectra of .beta.-naphthil in two different glasses at 77.degree.K have been resolved to their individual components by a computerized kinetic phosphorescence spectrometry system. Both the time-resolved spectrum which reveals the kinetic behavior of the excited states and the wavelength-resolved spectrum which tells the nature of the emitting species are obtained. Several possible emission mechanisms are discussed based on the informations gathered through the resolution processes. Triplet-triplet annihilation is shown to exist in solutions of benzophenone as well as in solutions of .beta.-naphthil. As concluded from the results of time-resolved study, such kind of interaction is responsible for the non-exponential distorsion of the decays. And according to the wavelength-resolved studies, transoid and cisoid conformational isomers seem to account for the sources of the dual emission of .beta.-naphthil.
