| Abstract: | The fluorescence
resonance energy transfer from proflavine hemisulphate to rose bengal in
aqueous sodium dodecyl sulfate has been investigated at room temperature using
steady-state
fluorescence spectroscopy technique. The fluorescence of
proflavine hemisulphate is quenched by rose bengal and the quenching is in
accordance with Stern-Volmer relationship. The efficiency of energy transfer is
found to depend upon
concentration of rose bengal. The value of critical energy transfer distance
calculated by using Foster relationship (27.2 Å) is less than 50 Å, indicating
efficient energy transfer occurs in this
donor-acceptor pair. |
