英文摘要	yellow-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.
