| Abstract: | The fluorescence spectra in various solvents for trichromophoric rhodamine laser dyes, in which naphthalimide chromophores were connected with rhodamine 6G by-CH_2CH_2-, have been investigated. The fluorescence lifetimes of these dyes have been measured by singlephoton counting technique. The intramolecular energy transfer and charge transfer between antenna naphthalimide moieties and rhodamine has been discussed.; |
