“…Accordingly, the PL spectrum is comprised of two bands, peaking at approximately 2.8 eV in blue region and 2.1 eV in yellow-orange region, respectively. [2], which is attributed to radiative recombination between an electron on V X O and a hole on (V In , V O ) X in the In 2 O 3 nanostructures [1]. Also, the yellow-orange emission (about 2.1 eV) was previously observed from In 2 O 3 nanotowers [3].…”

Production of indium oxide (In2O3) whiskers at a very low temperature of 650• C was reported. The synthetic route was comprised of a thermal heating process of a mixture of In and Mg powders. We have investigated the structural properties of the as-synthesized nanowires by using X-ray diffraction and scanning electron microscopy. The product consisted of one-dimensional nanowires, with a crystalline cubic structure of In2O3. The photoluminescence measurement with the Gaussian fitting exhibited visible light emission bands centered at 2.1 eV and 2.8 eV. The peaks of the Raman spectrum were indexed to the modes being associated with cubic In2O3.

“…The major advantage of this method should lie in its ability to decrease the temperature from 1975 K (which is essential for ZnO powder to melt) to lower than 1000 K: more specifically, its advantage is in its potential for industrial production. This method can possibly be extended to preparation of many other semiconductor nanowires, such as In 2 O 3 [26], SiC [27], SiO 2 [28], Si 3 N 4 [29], etc.…”

ZnO nanowires doped with Mg have been successfully prepared on Au-coated Si (111) substrates using chemical vapor deposition method with a mixture of ZnO, Mg, and activated carbon powders as reactants at 850• C. The structural, compositional, morphological and optical properties of the samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, and photoluminescence spectroscopy. The nanowires are single crystalline in nature and preferentially grow up along [0001] direction with the average diameter and length of about 60 nm and several hundred micrometers, respectively, thinner and longer than the results of literature using the similar method. Room temperature photoluminescence spectroscopy shows a blueshift from the bulk band gap emission, which can be attributed to Mg doping that were detected by energy dispersive X-ray analysis EDX in the nanowires. Finally, the possible growth mechanism of crystalline ZnO nanowires is discussed briefly.

“…The solid is vaporized through heating, which is transported by a carrier gas that feeds the catalyst and source material for nanowire [31,40] growth. Thermal CVD has been utilized for the growth of a number of IO nanostructures like nanopyramids, nanorods, nanowires, nanobelts and nanotubes filled with indium metal, with good crystalline nature and controlled morphology [29,30]. Li et al [31] has reported the growth of IO nanostructures filled with metallic indium by the heating of In + In 2 O 3 precursor at 1573 K for 30 min, while the Si substrate was held at 973-1073 K. Different morphologies can be obtained by varying the deposition parameters like temperature, pressure, precursor etc.…”

This chapter provides a comprehensive review of metal oxide nanostructures, their growth and applications. These metal oxides are important transparent conducting materials that have drawn great attention in the scientific community owing to their high optical transparency (*85-95 %) in the visible region of spectrum along with high electrical conductivity (10 3 -10 4 Ω −1 cm −1 ). The combination of these properties make these materials suitable for many technological applications in solar cells, heat mirrors, transparent conducting electrodes, display devices and light emitting diodes. The metal oxide nanostructures, particularly nanowires and nanotubes, have also drawn considerable research interest as sensor material because of their high surface-to-volume ratio and suitable surface chemistry for verities of sensor applications. This has opened up potential applications of these materials in the area of environment control devices with high sensing response, low detection limit, low power consumption and high compatibility with microelectronic processing for IC's. Thus, 1-D metal oxide nanostructures have proven to be the most promising interface for communicating with the outer world. Different growth techniques and various growth models have been discussed for the growth of nanowires, metal-filled nanotubes, octahedrons and nanoflute structures. The article concludes with a glimpse of some recent work based on metal oxide photodetector especially in deep ultraviolet region (DUV) (<280 nm) which would provide futuristic application in optical switching, single photon detection and communication.
