Chiral metal-containing semiconductor nanocrystals: Construction, optical activity, and application

In recent years, chiral semiconductor nanocrystals (NCs) have attracted extensive interest from researchers and significant research progress has been made. In order to provide researchers with a comprehensive and in-depth perspective in this topic, this review will summarize the recent research progress in the chiral semiconductor NCs, including synthesis methods, chiral mechanism, and relevant application. First, this review will discuss the construction strategies of various chiral semiconductor NCs. Second, the optical activities of different types of chiral semiconductor NCs, such as circular dichroism and circularly polarized luminescence, will be analyzed in depth, and the chiral origins will be discussed at the microscopic level. Third, we will summarize the applications of chiral semiconductor NCs in optoelectronic devices, nonlinear optics, and biomedicine. Finally, we will discuss the opportunities and challenges in the study of chiral semiconductor NCs.
