“…Among many nanoscale semiconducting materials, zinc oxide (ZnO) is a typical n-type inorganic semiconductor that displays a hexagonal crystalline wurtzite-type structure, with space group P6 3 mc and lattice parameters of a = b = 0.3250 nm and c = 0.5207 nm [1]. The importance of ZnO is due to its high conductance, good mechanical and thermal stability, wide and direct band gap of 3.37 eV and a large exciton binding energy of 60 MeV [2][3][4]. In addition, it has good radiation resistance and is harmless to the environment [5,6].…”

“…The diffractogram shows that the product formed exhibit the characteristic diffraction peaks of ZnO with hexagonal wurtzite structure (space group P6 3 mc). These peaks are probably related to the crystalline planes (100), (101), (110) and (103) According to previous studies 17,18 , depending on the concentration of the precursor solution, the nanostructures prepared by chemical or electrochemical methods may exhibit in their composition ZnO particles mixed with other phases such as Zn(OH) 2 Transmission electron microscopy was used to examine the morphological characteristics of the product synthesized at 90 °C employing Zn(NO 3 ) 2 .6H 2 O as precursor (Figure 3). The image shows the presence of short nanoprisms and nanorods.…”

“…ZnO has hexagonal wurtzite structure, lattice parameters a = 3.2539 Å and c = 5.2098 Å, and belongs to the space group P6 3 mc 1 . This material stands out among the semiconductors due to its large band gap (3.37 eV) associated with a high exciton binding energy (60 meV) 2,3 . Reducing the size of the ZnO to the nanoscale changes its properties significantly, since they are dependent on the size, orientation and morphology of the particles 4 .…”

This work evaluates the effect of ZnCl 2 and Zn(NO 3 ) 2 .6H 2 O as precursors in the synthesis of ZnO nanocrystals. The materials were obtained at 90 °C by a simple solochemical route. The resulting samples were characterized regarding phase composition, particle size and morphology, by means of XRD and TEM. The analysis have provided evidences that the material obtained applying Zn(NO 3 ) 2 .6H 2 O as precursor has hexagonal crystalline structure, typical of the ZnO, and dimensions in the nanoscale. However, applying ZnCl 2 as precursor results in a mixture of ZnO and Zn 5 (OH) 8 Cl 2 .H 2 O phases. For both precursors, the predominant morphology of the obtained ZnO nanocrystals was the rod-like structure.

Abstract. Nanosized Zinc oxide (ZnO) possesses unique electrical, optoelectronics and photochemical characteristics and thus it is a potential candidate for different applications in next generation of optoelectronic device. In this work, a novel sol-gel route for the synthesis of ZnO nanoparticles and its transformation into wires and bundles has been reported. The process is adopted from a simple and hand-on route that also shows the power of green chemistry in nanomaterials synthesis. ZnO nanoparticles (~30 nm in diameter) were synthesized from bottom-up approach followed by a further process to obtain nanometric wires and bundles under controlled conditions. The nanowires and bundles are speculated to initiate from anisotropic agglomeration of nanometric particles and agglomeration of these nanometric wires into bundles respectively. Control of these agglomeration processes is a key challenge for application of nanowires and bundles into useful devices.
