Abstract

Extending our stationary fluorescence and absorption measurements of petroleum products in cyclohexane solution, time-resolved measurements of the fluorescence decay are presented in this paper. Several parameters suitable for the description of fluorescence decay curves of petroleum products are discussed in detail. Measurements of time- resolved emission spectra indicate an emission-wavelength dependence of the decay curves. We have found that the fluorescence emission of petroleum products is significantly influenced by oxygen. Applying a Stern-Volmer analysis it is possible to obtain Stern-Volmer constants K_sv and quenching constants k_q for the quenching of the petroleum product fluorescence by molecular oxygen. In addition, the excitation-wavelength dependence of stationary fluorescence as well as the concentration dependence of the effective extinction coefficients have been investigated.
