摘要
We report studies of the homogeneous linewidth in CdSe/ZnS core/shell nanocrystals by means of high-resolution spectral hole burning under low excitation levels. The hole burning spectrum reveals a sharp spectral hole as well as clearly resolved acoustic phonon sidebands. Homogeneous linewidths as narrow as 32 mu eV were obtained. At low temperature, the temperature dependence of the homogeneous linewidth deviates from the usual linear dependence, reflecting the effects of phonon quantization.
