AbstractYellow-white light emitting diodes (LEDs) using ZnO nanocrystals (NCs) as the active materials have been fabricated based on a solution-processed technology. By utilizing a polar-nonpolar mixed-solvent dispersion strategy, uniform dispersion of ZnO NCs with enhanced emission properties has been achieved. The ZnO NCs based LED devices prepared from the mixed-solvent strategy show much improved electroluminescence properties that exhibit a broad yellow-white emission peaks at similar to 555 nm with a maximum brightness of 100 cd/m(2) and a color rendering index of 77.25. The device mechanism of the LED device was discussed in terms of energy band diagram and current-voltage characteristics. (C) 2015 AIP Publishing LLC.
