Circularly Polarized Luminescent Carbon Dot Nanomaterials of Helical Superstructures for Circularly Polarized Light Detection

Circularly polarized luminescent carbon dot nanomaterials of self-organized helical superstructures based on cellulose nanocrystals enable strong, right-handed, and multicolor tunable circularly polarized luminescence with extraordinary dissymmetry factors up to -0.74. The effects of emission intensity and carbon dots loading on the strength of the right-handed circularly polarized luminescence are experimentally observed and theoretically explained. Potentials of the carbon dots-cellulose nanomaterials for circularly polarized light detection are demonstrated.
