Blue light emitting ZnO-Graphene hybrid quantum dots and Method for the same and Light emitting diode using the same

摘要

The present invention relates to a zinc oxide graphene composite quantum dot capable of emitting blue light and a method for manufacturing the same, and a light emitting diode using the same, wherein the light emitting diode using the zinc oxide graphene composite quantum dot capable of emitting blue light according to the present invention is a blue light emitting light. The zinc oxide graphene composite quantum dot capable of using this as a light emitting layer, the zinc oxide graphene composite quantum dot capable of emitting blue light, the zinc oxide quantum dot and graphene is a form of a combination of Zn-OC bond, intrusion type Zn Atomic (Zn _i ) energy level, excited Zn atom (Zn _i^* ) energy level, Zn public (V _Zn ) energy level and Zn-OC energy level are present, and the excited electrons are Zn atoms (Zn _i) ) energy level, the excited interstitial Zn atoms (Zn _i^*) energy level, Zn-OC at least one of the energy levels public Zn _(Zn V) as a transition to the electronic energy level to a blue-based color It characterized in that the two would be possible.
