Organic light-emitting diode (OLED)currently provide display platform with high-resolution such as 4 and 8 Kresolution and flexibility. However, they still have some critical issues suchas burn-in and operational lifetime. Recently, quantum dot-based light-emittingdiodes (QD-LED) have been drawn attention to be a promising candidate of lightemission devices for enabling high brightness, wide spectral tenability, andcolor saturation. With this regard, herein, we propose that multicolor emissivecarbon quantum dots (CQDs) can be adopted as emissive materials due to their superioroptical properties such as tunable (430 – 670 nm) and narrow-bandwidth (> 40nm) in emission material layer (EML) in QD-LED devices. In addition, thesynthetic processes for mass production of CQD with multiple color emissionhave been developed by a simple chemical treatment, which can be achieved tolay the groundwork for the next-generation display technologies to realize ourreal colors. |
