“…Figure shows the UV−visible spectra of as-prepared samples. The absorption spectrum (Figure 8A) of the ZnO nanowires showed the presence of a maximum absorption peak at 364 nm, which blue-shifted relative to that of the corresponding signal for bulk ZnO, in agreement with prior work. , By analogy, the maximum absorption peaks of CuO nanowires and of α-Fe 2 O 3 nanotubes (Figure B and C) were noted at 205 and 208 nm, respectively, which also showed a blue-shift relative to that of their bulk counterparts, consistent with previous reports. , Essentially, with decreasing sample size, the optical edge shifts to higher energy, a phenomenon attributable to quantum size and confinement effects . Indeed, a size-dependent blue-shift has been observed in the absorption spectra of nanocrystalline motifs of many other bulk materials, such as TiO 2 nanowires …”

ZnO nanowires, CuO nanowires, and alpha-Fe(2)O(3) nanotubes as well as their corresponding arrays have been successfully synthesized via a low cost, generalizable, and simplistic template method. Diameters of one-dimensional (1-D) metal oxide nanostructures ( approximately 60-260 nm), measuring micrometers in length, can be reliably and reproducibly controlled by the template pore channel dimensions. Associated vertically aligned arrays have been attached to the surfaces of a number of geometrically significant substrates, such as curved plastic and glass rod motifs. The methodology reported herein relies on the initial formation of an insoluble metal hydroxide precursor, initially resulting from the reaction of the corresponding metal solution and sodium hydroxide, and its subsequent transformation under mild conditions into the desired metal oxide nanostructures. Size- and shape-dependent optical, magnetic, and catalytic properties of as-prepared 1-D metal oxides were investigated and noted to be mainly comparable to or better than the associated properties of the corresponding bulk oxides. A plausible mechanism for as-observed wire and tube-like motifs is also discussed.

“…A broad peak at 36.87 o associated with ZnO (101) crystallographic plane is observed, which clearly demonstrate that the film deposited in oxygen atmosphere has a dominant (101) orientation [11].The absorption spectra of ZnO nanostructures deposited on the glass substrate is depicted in Figure 3. In the absorption spectra of ZnO film deposited on the glass substrate and oxidized at 400 o C, the presence of oxygen shows a broad peak with the blue shift to 373 nm wavelength [12]. This broad peak is accounted for the conversion of Zn into ZnO when the film is oxidized which corresponds well with the XRD data.…”

Nanostructures of zinc oxide are synthesized by physical vapor condensation method. From the SEM image, it is observed that these nano structures look like nanosprings mixed with nanorods. The typical diameter of these nanostructures is in the range of 80-150 nm and the length is of the order of several micrometers. The XRD data shows a sharp peak at 36.87 o which is very close to that of zinc oxide nanorods grown by oxidation in the presence of ambient gases i.e. oxygen mixed with argon. UV visible spectra of these nanostructures shows a peak at 371 nm and 373 nm. The broad peak at 373nm is responsible for the conversion of zinc into zinc oxide.
