Abstract

Carbon quantum dots (CQDs) have shown great potential in optoelectronic applications. Very recently, CQDs have attracted much attention in white-emitting diodes (WLEDs) for lighting due to their characteristic broad emission, tunable fluorescence emission and high thermal stability. This mini review updates the latest research in the design of high-performance WLEDs with different correlated color temperatures by tuning the red component using red emissive CQDs and single-component white emissive CQDs (SCWE-CQDs). The prospects for the development of CQD based WLEDs with higher efficiency and color quality will be discussed.

摘要

碳量子点（CQDs）在光电子应用中已展现出巨大潜力。最近，由于其特征性的宽发射、可调谐荧光发射和高热稳定性，碳量子点在用于照明的白色发光二极管（WLEDs）中备受关注。本综述更新了通过使用红色发射碳量子点和单组分白色发射碳量子点（SCWE-CQDs）调节红色成分来设计具有不同相关色温的高性能WLEDs的最新研究。还将讨论基于碳量子点的WLEDs在提高效率和颜色质量方面的发展前景。
