Abstract
The invention discloses a visible light excited dual-mode long-afterglow carbon dot compound as well as a preparation method and application thereof. The prepared carbon dots are doped into boron oxide grids in the high-temperature heating process, carbon-boron bonds are formed, inter-system jump is promoted, and the obtained CDs/B2O3 compound can obtain long-afterglow delayed fluorescence and room-temperature phosphorescence emission at the same time under visible light excitation, and the CDs/B2O3 compound with visible light excited delayed fluorescence and room-temperature phosphorescence has potential in the aspect of potential fingerprint identification.
