Synthesis and local structure of doped nanocrystalline zinc oxides

Substrate‐Free Fabrication of Self‐Supporting ZnO Nanowire Arrays

“…It has been demonstrated that ZnO nuclei possess a “fourling” structure19 from which multiple (ideally four or seven) spines will possibly develop along their own [001] directions 20. If those spines are able to grow unconstrained under hydrothermal conditions, star‐like or flower‐like ZnO particles or nanostructures are produced, which have been reported extensively in previous literature,18, 21 and also exist in our films (e.g.…”

Effect of exposure time on the growth of self-supporting ZnO nanowire arrays and their photocatalytic behavior

“…Fig. 3 displays the SEM images of the films prepared by exposed to atmosphere for 6,9,12,15,18,21 compact density of the ZnO NWAs increases and the diameter decreases. In addition, when the exposure time reaches 15 min, the ZnO NWAs exhibit the most uniform, dense, and thin arrays.…”

“…It has been demonstrated that ZnO nuclei possess a "fourling" structure [21] from which multiple spines will possibly develop along their own [0 0 1] directions. After the cover glass was removed, the initiation of fourlings started by homogeneous nucleation near the solution surface.…”

Effect of Gallium Concentrations on the Morphologies, Structural and Optical Properties of Ga-Doped ZnO Nanostructures

“…It is predicted that the secondary growth might be due to the fact that the ionic radius of Ga (∼ 0.62 Å) is smaller than the ionic radius of the Zn (∼ 0.74 Å) so when a large number of Ga ions is incorporated into the lattice of the ZnO they cause strain and hence distortion of the primary growth. [22][23][24][25] This distortion helps in the formation of multipod structures as the distorted sites of the crystal act as the active sites for the secondary growth.…”
