Radiative Life-time of the Pyrene Dimer and the Possible Role of Excited Dimers in Energy Transfer Processes

Nature volume 186, pages 1045–1046 (1960)Cite this article

Abstract

THE absorption spectra of certain dye solutions exhibit a marked dependence on concentration over a range in which the corresponding fluorescence spectrum remains unchanged; this is attributed to absorption by non-fluorescent dimeric complexes at higher concentration which reduces the overall fluorescence yield of the solution1. The relative intensities of absorption by the dye in its monomeric and dimeric forms suggest that the radiative lifetimes of the corresponding excited species are both of the order of 10−8–10−9sec. (ref. 2).
