Sensitive Method

Four methods of applying mode-locked lasers to time-resolved fluorescence measurements in the subnanosecond region are compared. When time resolution below 100 ps is not required, the most precise and sensitive method is single-photon counting, and the application of this method to studies of time-resolved fluorescence of tryptophan in simple peptides is described. The dependence of lifetimes on pH and temperature are interpreted in terms of quenching by intramolecular proton and electron transfers.

Hopping Model

The time-resolved fluorescence of tetracene crystals excited by a single 7-ps pulse of 530-nm light has been measured with a streak camera/OMA system. The singlet exciton lifetime was found to be 300�30 ps at 293 K. Singlet-singlet exciton annihilation was observed, and the rate constant found to be 5 x 10-9 cm3 s-1. In order to fit the observed decay curves, an upper limit of c. 1 x 10-9 cm3 s-1 must be set on the singlet-triplet exciton annihilation rate. The measured singlet-singlet exciton annihilation rate is consistent with a hopping model for singlet exciton motion at room temperature.
