▎ 摘　　要

NOVELTY - Zinc oxide-based quantum dot aggregate comprises a zinc oxide quantum dot and a zinc oxide-graphene quantum dot in mixture, where the zinc oxide quantum dot emits yellow light when being irradiating an excitation wavelength shorter than a wavelength corresponding to an energy band gap of the zinc oxide quantum dot. The zinc oxide-graphene quantum dot is in a form in which a zinc oxide quantum dot is bound with graphene through a zinc-oxygen-carbon (Zn O C) bond and emits blue-based light and white light emission is possible through color rendering of yellow light emission by the zinc oxide quantum dot and blue-based light emission by the zinc oxide-graphene quantum dot. USE - Zinc oxide-based quantum dot aggregate is used for emitting white light. ADVANTAGE - The zinc oxide-based quantum dot aggregate utilize the electronic transition between the natural intrinsic defects present inside the bandgap, namely, in the intra-band among the oxide quantum dots having a band gap value of about from 3.0-4.0 electrovolt which is not too great.
