报道了部分抑制量子点激子在纳米光子腔中共振时的光谱扩散。这种抑制是由于Purcell对量子点激子复合率的增强，从而改变了量子点本身对固态环境的充电速度。这种效应可以用来光谱稳定单光子和其他非经典光的固态发射体。
Partial suppression of the spectral diffusion of quantum dot (QD) excitons tuned to resonance of a nano-photonic cavity is reported. The suppression is caused by the Purcell enhancement of the QD-exciton recombination rate, which alters the rate of charging of the solid-state environment by the QD itself. The effect can be used to spectrally-stabilize solid-state emitters of single photons and other non-classical states of light.
