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 , which is the best performance for CQD-based monochrome electroluminescent LEDs.
采用溶剂热法合成了具有高达 75%量子产率的从蓝色到红色的多色带隙荧光碳量子点（MCBF-CQDs）。首次制备了以 MCBF-CQDs 直接作为有源发射层的单色电致发光二极管（LED）。蓝色 LED 的最大亮度达到 136 cd m ，这是基于 CQD 的单色电致发光 LED 的最佳性能。
