Preparation of electrically conductive nano-powder of zinc oxide and application to transparent film coating

A Review of Conductive Metal Nanomaterials as Conductive, Transparent, and Flexible Coatings, Thin Films, and Conductive Fillers: Different Deposition Methods and Applications

“…Several metal NPs have been investigated by researchers for use as conductive nanomaterials. Zinc oxide (ZnO) NPs were introduced by Izumi and his co-workers as a conductive nanomaterial [52]. In terms of cost and safety, ZnO NPs are a promising alternative to ITO.…”

Electrolytic Synthesis of Al‐Doped ZnO Nanopowders With Low Electrical Resistivity

“…Among these dopants, doping of Al has been very popular because it produces highly conductive ZnO with high transparency in the visible spectral region due to the close covalent bond length of Al–O (0.192 nm) to that of Zn–O (0.197 nm) 6,7 . Several authors have already reported the synthesis of Al‐doped ZnO (AZO) nanopowders, such as ball milling, 8,9 coprecipitation, 10 wet process in aqueous solution, 11 combination of powder mixing method and colloidal method, 12 hydrothermal and vapor condensation methods, 13 solid‐state reaction technique, 14 and precursor process 15…”

“…4 The electrical resistivity of ZnO can be decreased by doping trivalent atoms such as Al, In, and Ga, whereas it is increased by doping monovalent atoms such as Li and K. 5 Among these dopants, doping of Al has been very popular because it produces highly conductive ZnO with high transparency in the visible spectral region due to the close covalent bond length of Al-O (0.192 nm) to that of Zn-O (0.197 nm). 6,7 Several authors have already reported the synthesis of Al-doped ZnO (AZO) nanopowders, such as ball milling, 8,9 coprecipitation, 10 wet process in aqueous solution, 11 combination of powder mixing method and colloidal method, 12 hydrothermal and vapor condensation methods, 13 solid-state reaction technique, 14 and precursor process. 15 In the present work, we report the fabrication, physical properties, and characterization of AZO nanopowders prepared by electrolytic synthesis.…”

Preparation and DSC application of the size-tuned ZnO nanoarrays

“…Zinc oxide (ZnO), as a semiconductor with a wide band gap of 3.37 eV and the higher exciton binding energy (60 meV) at room temperature, has attracted great interest due to its special properties and potential applications in such fields as chemical sensors [1], dye-sensitized solar cells [2], nanogenerators [3], nanolasers [4], and transparent film coating [5].…”
