Abstract

A facile synthetic approach to prepare environmentally friendly white fluorescent carbon dots (CDs)/ZnO quantum dots (QDs) composites through electrostatic force is described. This method can be used for fabrication of high-performance white light-emitting diodes (WLEDs). The fluorescence emission spectra of WLED devices covered a range from 425 nm to 750 nm. WLEDs had a CIE chromaticity coordinate of (0.30, 0.34) and a color temperature of 7093 K.
