Abstract: Disclosed are a nano metal oxide and a manufacturing method therefor, a quantum dot light emitting diode. The manufacturing method comprises the following steps: (S100) providing a composite material, the composite material comprising PAMAM dendrimers and metal ions bonded in the PAMAM dendrimer cavities; (S200) adding the composite material into a growth reaction system for nano metal oxide and mixing so as to obtain the nano metal oxide. The method can realize the uniform doping of metal ions into a nano metal oxide so as to obtain the nano metal oxide with less defects and better quality. The nano metal oxide is used as the material for the electron transfer layer of the quantum dot light emitting diode to adjust the electronic mobility of the quantum dot light emitting diode, thereby balancing the hole injection velocity of electrons and improving the light emitting efficiency.
