摘要：

Herein, we directly prepared white fluorescent CDs (W-CDs) using 1,6-dihydroxynaphthalene (1,6-DHN) and L-asparagine (L-Asn) as carbon sources through a simple solvent-free method. As-prepared W-CDs can be obtained in high yield (95%). A relative pure white LEDs (WLEDs) were fabricated with Commission Internationale de L'Eclairage (CIE) coordinates of (0.32, 0.31). As-prepared W-CDs will have promising future for a wide range of optoelectronic devices. (C) 2021 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
