Optical properties of ZnO nanostructures.
TL;DR: A review of current research on the optical properties of ZnO nanostructures and results of nonlinear optical studies, such as second-harmonic generation, are presented.
Journal ArticleDOI
Controlled growth of tetrapod-branched inorganic nanocrystals
TL;DR: It is demonstrated that polytypism, or the existence of two or more crystal structures in different domains of the same crystal, coupled with the manipulation of surface energy at the nanoscale, can be exploited to produce branched inorganic nanostructures controllably.

Gas sensors using hierarchical and hollow oxide nanostructures: Overview
TL;DR: In this article, the authors show that hierarchical and hollow oxide nanostructures increase both the gas response and response speed simultaneously and substantially, which can be explained by the rapid and effective gas diffusion toward the entire sensing surfaces via the porous structures.
Journal ArticleDOI
ZnO nanorods: synthesis, characterization and applications
TL;DR: A review of current research activities on ZnO nanorods (or nanowires) can be found in this paper, where a wide range of interesting properties such as luminescence, field emission, gas sensing and electron transport, as well as various intriguing applications are discussed.
