Abstract :
Measurements were made of the time-dependent gain in flashlamp-pumped rhodamine 6G/ethanol solutions saturated with air and with nitrogen. Fitting of transient gain data to theory showed that dissolved oxygen increased the rate of triplet generation as well as accelerating the return of triplets to the ground state. Large transient absorption was observed in fluorescein solution at all oxygen concentrations but it was removed by adding anthracene or cyclooctatetraene.
