Formation of self-aligned ZnO nanorods in aqueous solution

Room temperature synthesis of ZnO nanoflowers on Si substrate via seed-layer assisted solution route

“…Manipulation of their sub-structure and morphology has arisen many interests in recent years [8,9]. So far, a variety of Zn nanostructures such as nanowires, nanorods, nanodots, nanotubes, nanosheets, nanobelts, nanoribbons, nanorings, nanoaeroplanes, nanocombs, nanobridges and nanonails have been synthesized via various physical and chemical fabrication techniques [10][11][12][13][14][15]. These methods include vapor phase transport process, chemical vapor deposition, thermal evaporation process, electrodeposition, hydrothermal, self-assembly, and template-assisted sol-gel process [16][17][18][19][20][21].…”

Formation of ZnO nanorod arrays on polytetraflouroethylene (PTFE) via a seeded growth low temperature hydrothermal reaction

“…In a hydrothermal process, the vapour-liquid-solid (VLS) growth mechanism, which is often used to explain the formation of ZnO nanorods or nanowires in physical deposition processes, is not applicable [11]. Instead, the growth of the rods is thought to occur by a solid-liquid-solid (SLS) mechanism [11][12][13][14].…”

Synthesis of heavily doped nanocrystalline ZnO:Al powders using a simple soft chemical method

“…, it is possible to control the morphology, particle size and chemical composition of the ZnO nano powder by controlling the level of doping during synthesis. Several new routes have been developed for the synthesis of ZnO nanoparticles such as sonochemical method [19], oxidation process [20], sol-gel synthesis [21] organochemical route [22], colloid chemistry [23], precipitation [24], hydrothermal micro emulsion [25], hydrothermal method [26], solution combustion method [27], solid state reaction [28], thermal evaporation [29] and wet chemical method [30] etc. In this study, the wet chemical method is employed for the synthesis of undoped and Al doped ZnO (AZO) nanoparticles, because it provide a simple and economic route as well as requiring low temperature.…”
