Abstract
Fast exciton quenching by methyl viologen (MV2+), an electron acceptor, on the CdSe quantum dot surface impulsively induces acoustic vibration via the mechanism of inverse piezoelectric effect, thereby causing an increase in the amplitude of the coherent acoustic phonon in the CdSe/MV2+ system compared to pure CdSe.
