TEMPERATURE EFFECT ON THE FLUORESCENCE-SPECTRA OF 2-COMPONENT VISCOUSSOLUTIONS IN THE PRESENCE OF FORWARD AND REVERSE NONRADIATIVE EXCITATION-ENERGY TRANSPORT

The influence of temperature on the forward and reverse nonradiative e xcitation energy transport (NEET) was studied in the system of rhodami ne 6G (R6G, donor) and rhodamine B (RB, acceptor) in glycerol using st eady-state techniques. It was found that the reverse energy transfer e ffectiveness decreases with the increase in temperature. It is shown t hat the temperature quenching is responsible for this regularity and o ther effects, like the increase in the orientation factor and the ther mochromic shifts of the spectra in the system investigated are of mino r importance.
