摘要：
We report experimental studies of exciton dephasing in self-assembled CdSe quantum dots using techniques based on spectral hole burning. The hole-burning response reveals directly in the spectral domain the zero-phonon-line (ZPL) as well as contributions from acoustic and LO-phonon assisted transitions. The observed strong coupling to acoustic phonons is in good agreement with theoretical expectation. The measured decoherence rate associated with the ZPL is as small as 3.5 mueV, comparable to that in self-assembled InGaAs quantum dots.
