Abstract
We report novel effect of solvents on optical coherence properties of CdSe/ZnS semiconductor quantum dots (QDs) in solution detected by femtosecond four-wave mixing (FWM) spectroscopy. The FWM signals of QDs show different time profiles and femtosecond coherence decays in three solvents. Our findings provide definite evidence that the interaction with solvent molecules predominantly determines optical coherence and line broadening properties of QDs in solution.
