In this paper we report the use of the dual beam thermal lens technique as a quantitative method to determine absolute fluorescence quantum efficiency and concentration quenching of fluorescence emission from rhodamine 6G doped Poly(methyl methacrylate) (PMMA), prepared with different concentrations of the dye. A comparison of the present data with that reported in the literature indicates that the observed variation of fluorescence quantum yield with respect to the dye concentration follows a similar profile as in the earlier reported observations on rhodamine 6G in solution. The photodegradation of the dye molecules under cw laser excitation is also studied using the present method.

Über die Fluoreszenzfähigkeit von Triphenylcarboniumderivaten / Fluorescence Yields of Triphenylcarbonium Derivatives

The absolute fluorescence yields of triphenylcarbonium derivatives are correlated with the change of bond order between central-C-atom and phenyl group during the electronic transition. The fluo rescence yield is reduced by a rotation of the phenyl group only if the π-electron system of the phenyl group is sufficiently strong coupled to the other part of the molecule. The change of bond order can be assumed as a measure for the coupling.
