  • The temperature dependence of fluorescence has been measured for eight crude oils in the temperature range 20-200 °C and for related compounds in the temperature range -80 to 200 °C. The measurements show that crude oils fluoresce strongly at elevated temperatures but more weakly than at room temperature. Furthermore, elevated temperatures produce very little effect on the spectral distribution of fluorescence. The decrease in fluorescence intensity is explained using a simple theoretical model which consists of Arrhenius activation of thermal quenching of fluorescence coupled with a Boltzmann distribution of molecular complexes. © 1992, American Chemical Society.
