recehezl 113fay 1978 Fluorescence liie5rne measurements of rhodamine B in ethanol solution have confirmed the presence of tuo distinct species dependent on acidity. RotationaI diffusion tnnes of these species are identical and ue propose that they are the acid and base forms of -he dye\_ Species hav
Photophysics and spectral characteristics of the zwitterionic and cationic forms of rhodamine B have been studied in a number of protic and aprotic solvents with different solvation properties. The results have been discussed on the basis of the molecular structures of the dye, role of carboxyphenyl
Deactivation processes of Rhodamine B (RB) in water and interacting with silver sols were studied by using conventional fluorescence, laser-induced fluorescence, and pulsed laser photoacoustics. Results showed that the emission efficiencies, absorption cross sections, and nonradiative deactivation p
Steady-state and time-resolved absorption and fluorescence spectra of evaporated rhodamine B layers (pure and mixed with NaF) were compared with RhB-polymer layers. Excitation spectra allow for the analysis of aggregate structures. Light harvesting is accomplished via energy transfer from high-lying
