HETEROSTRUCTURE OF LUMINESCENCE ZNO NANO-WIRE COMPRISING ZNS QUANTUM DOT AND METHOD FOR FABRICATING THE SAME

摘要

A heterostructure of light-emitting nano-wires is provided to realize a light-emitting effect in a broader range of visible light wavelengths than the range of light emitted from pure zinc oxide nano-wires. A heterostructure(10) of light-emitting nano-wires comprises zinc sulfide(ZnS) quantum dots(110) randomly distributed on the surface of zinc oxide(ZnO) nano-wires(100), and emits light in an intermediate wavelength range between the main wavelength range of the light emitted uniquely by zinc oxide and the impurity level wavelength range of the light emitted by zinc sulfide. The intermediate wavelength range is 410-420 nm.
