Red emissive carbon quantum dots (R-CQDs) with quantum yield of 53% is successfully prepared. An ultraviolet-pumped CQD phosphors-based warm white-light-emitting diode (WLED) is realized for the first time and achieves a color rendering index of 97. This is reported by Zifei Wang, Fanglong Yuan, Xiaohong Li, Yunchao Li, Haizheng Zhong, Louzhen Fan, and Shihe Yang in the article https://doi.org/10.1002/adma.201702910, and provides a new avenue for the exploration of low cost, environment-friendly, and high-performance CQD phosphors-based warm WLEDs.
