Title: Chiral semiconductor nanomaterials and chiral optical property
Abstract:
Circularly polarized luminescence (CPL) has special polarization state and angular momentum, and has application prospects in many frontier fields such as quantum computing and 3D stereoscopic display. However, the reported materials do not own both high magnetic transition dipole moment and electric transition dipole moment simultaneously, resulting in low CPL intensity and asymmetry factor. Besides,white CPL is hard to realize. Therefore, it is a challenging issue that how to obtain efficient CPL system and realize the regulation and improvement of CPL performance in CPL field. In this project, chiral monoamines and diamines with different steric effect and configurations are designed to construct 0D-2D perovskite with high CD intensity. The low dimension and crystal plane orientation and structural distortion regulated by hydrogen bond, together lead to broadband self-trapping effect based CPL. Some of the chiral crystals show second harmonic generation due to the chiral space group, i.e. non-centrosymmetric crystal structure.
