Abstract
A method for manufacturing a Zinc oxide nanocapsule includes: a step of preparing a Zinc oxide narorod; a step of etching the Zinc oxide narorod to form a Zinc oxide nanotube, wherein the Zinc oxide nanotube is a hollow tubular structure; a step of filling a material into the Zinc oxide nanotube; and, a step of regrowing the Zinc oxide nanotube to encapsulate the hollow tubular structure so as to form a Zinc oxide nanocapsule. In addition, a zinc oxide nanocapsule is also provided.
