Multicolor bandgap fluorescent carbon quantum dots (MCBF-CQDs) from blue to red with quantum yield up to 75% are synthesized using a solvothermal method. For the first time, monochrome electroluminescent light-emitting diodes (LEDs) with MCBF-CQDs directly as an active emission layer are fabricated. The maximum luminance of blue LEDs reaches 136 cd m-2 , which is the best performance for CQD-based monochrome electroluminescent LEDs.

• On the Emission Properties of Carbon Dots: Reviewing Data and Discussing Models (2019, methodology): “With very few exceptions [57,58], the PL decay is a non-single exponential, an indication of multiple contributions to the overall emission and also of non-radiative pathways being accessibile to the whole PL spectrum.”
