Abstract: a b s t r a c tHigh-density hierarchical brush-like nanostructures of Ce-doped ZnO are first synthesized by a two-step approach (sol-gel and chemical vapor deposition). This novel structure, called nanobrush, is a new member in the family of hexagonal crystal ZnO nanostructures, which is composed of two parts: a micronsized prism-like base and nano-sized vertical nanorod arrays.The nanobrush is enclosed by the (0001) and {0110} facets and grows towards the [0001] direction. Room-temperature photoluminescence …
