“…Therefore, depending on the interfacial interaction with the substrates and directional growth of ZnO NRs, the UV emission can be blue shifted or red shifted from the NBE (381 nm) within a certain range. Apart from this UV emission, we have also observed the blue emission at 455 nm from Si and 466 nm from ITO and quartz samples which are related to oxygen vacancy defect emission, as explained by many authors [26][27][28]. However, the ZnO NRs on MgO substrates do not show any defect emission peak which might be interesting for UV optoelectronic devices.…”

“…There are many reports [1][2][3][4][5][6][12][13][14][15][16][17][18][26][27][28] on near band edge (NBE) emission peak at 381 nm and assigned to free exciton emission. Park et al [28] reported that at low temperature (40 K) three peaks at 373, 381 and 391 nm correspond to the ZnO seed layer on which ZnO nanowires were grown, an NBE peak responsible for recombination of free excitons, and a donor-acceptor pair (DAP) respectively. Li et al [17] observed 372 nm peak from disperser ZnO quantum dots in ZnO nanofibers.…”

We report the hexagonal wurtzite crystalline structure of ZnO nanorod growth by hydrothermal chemical wet synthesis at low temperature (90 C). We have used p-Si (100), n-Si (100), -quartz (0001), MgO (0001) and ITO (polycrystalline) substrates to understand the growth mechanism of ZnO nanorods with a low pressure environment. X-ray diffraction study confirms the hexagonal structure of the ZnO nanorod. Scanning electron microscopy (SEM) also shows the hexagonal structure along with different size and width of the nanorods. The substrate effect of nanorods has been explained on the basis of adatom kinetics during the growth. We observed that the nanorods were grown from a single nucleation point with 4-5 different branches on the ITO substrate with uniform length and width, whereas MgO substrate shows curled flower architecture across the whole area. The photoluminescence illustrates strong substrate effect. A wide range of UV emission bands along with visible emission has been observed from the ZnO nanorods deposited on different substrates.

“…Another effect of mechanical activation is the formation of well-crystallized structures in nanowires and nanotubes. High-quality, single-crystalline GaP nanowires and ZnO nanobelts are formed from the milled GaP and ZnO starting powders while polycrystalline curled GaP nanowires or ZnO plateshaped chips are obtained from the unmilled powders [47,48].…”

One-dimensional (1D) nanomaterials including nanotubes, nanowires and nanorods have many new properties, functionalities and a large range of promising applications. A major challenge for these future industrial applications is the large-quantity production. We report that the ball milling and annealing process has the potential to achieve the mass production. Several examples including C, BN nanotubes and SiC, Zn nanowires are presented to demonstrate such capability. In addition, both size and structure of 1D nanomaterials can be controlled by varying processing conditions. New growth mechanisms involved in the process have been investigated and the highenergy ball milling has an important role in the formation of these 1D nanomaterials. r

semiconductor nanowires were synthesized by a variety of growth methods, and they were wrapped cylindrically with amorphous aluminum oxide (Al 2 O 3 ) shells. The Al 2 O 3 was deposited on these seven different semiconductor nanowires by atomic layer deposition (ALD) at a substrate temperature of 200°C using trimethylaluminum (TMA) and distilled water (H 2 O). Transmission electron microscopy (TEM) images taken for the nanowires revealed that Al 2 O 3 cylindrical shells surround uniformly all these semiconductor nanowires. Our TEM study illustrates that the ALD of Al 2 O 3 has an excellent capability to coat any semiconductor nanowires conformally; its coating capability is independent of the chemical component, lattice structure, and growth direction of the nanowires. This study suggests that the ALD of Al 2 O 3 on nanowires is one of the promising methods to prepare cylindrical dielectric shells in coaxially gated, nanowire field-effect transistors (FETs).
