A research group led by Prof. Wu Kaifeng and Zhu Jingyi from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences recently reported the observation of an excitonic Bloch-Siegert shift in CsPbI3 perovskite quantum dots (QDs), which advances current fundamental understanding for coherent light-matter interaction in low-dimensional solid-state materials.
