Spectroscopy and carrier dynamics of one-dimensional nanostructures

In recent years, one-dimensional (1D) nanomaterials have raised researcher's interest because of their unique structural characteristic to generate and confine the optical signal and their promising prospects in photonic applications. In this review, we summarized the recent research advances on the spectroscopy and carrier dynamics of 1D nanostructures. First, the condensation and propagation of exciton–polaritons in nanowires (NWs) are introduced. Second, we discussed the properties of 1D photonic crystal (PC) and applications in photonic–plasmonic structures. Third, the observation of topological edge states in 1D topological structures is introduced. Finally, the perspective on the potential opportunities and remaining challenges of 1D nanomaterials is proposed.
