我们报告的均匀线宽的CdSe/ZnS核/壳纳米晶体的高分辨率光谱烧孔低激发水平下的装置的研究。烧孔光谱揭示了一个尖锐的光谱孔，以及清楚地解决声学声子边带。获得了窄至32 μeV的均匀线宽。在低温下，均匀线宽的温度依赖性偏离通常的线性关系，反映了声子量子化的影响。
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 μeV were obtained. At low temperature, the temperature dependence of the homogeneous linewidth deviates from the usual linear dependence, reflecting the effects of phonon quantization.
