Enhanced UV activation of electrochemically doped Ni in ZnO nanorods for room temperature acetone sensing

Growth of ZnO Nanorod Arrays on Flexible Substrates: Effect of Precursor Solution Concentration

“…The zinc oxide nanorods were prepared by a two-step process which was similar to the procedure reported in the literature [17,18]. In the first step, ZnO seed layer with an approximate thickness of 40 nm were radio-frequency (RF) sputtered on the flexible ITO substrates.…”

“…Due to the high surface-to-volume ratio provided by the one-dimensional (1D) nanostructure, ZnO nanorod arrays are considered suitable to the application for hybrid photovoltaic devices [4][5][6][7]. In the past few years, ZnO nanorods have been synthesized via various physical and chemical methods including vapor phase synthesis [8][9][10], metalorganic chemical vapor deposition (MOCVD) [11][12][13], and solution-based synthesis [14][15][16][17]. Among these routes, solution-based method has the advantages of simplicity, low costs, low growth temperature, and easy coating of large surfaces Intensive research has been focused on the solution growth process of ZnO nanorods on ITO-coated glass substrates.…”

“…The aqueous solution contains equimolar of zinc nitrate and hexamethylenetetramine (HMT), which are the main chemicals used by many research groups [16,17,22] in solution growth of ZnO nanorods. One of the major merits of this aqueous solution method is the use of distilled water instead of using alcohol as the solvent, since water is more inexpensive and environmentally friendly [23].…”

Flash synthesis of Al-doping macro-/nanoporous ZnO from self-sustained decomposition of Zn-based complex for superior gas-sensing application to n-butanol

“…A majority of researches have reported that doping chemical elements such as Ni, Mn, Al, Bi, Cr and Pr in hexagonal wuritzite ZnO can promote its selectivity and response to objective gases [16], change the crystalline state [13], and improve electrical conductivity [17]. Among them, Al-doped ZnO materials show a high electrical conductivity and excellent optical properties [18], making it a promising candidate for gas monitoring.…”

Shape-controlled magnetic nanoplatelets of Ni-doped ZnO synthesized via a chemical precursor

“…Such small particles show many distinct features because of the large fraction of atoms present in the M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT grain surfaces or boundaries. In this regard, ZnO based DMS materials are highly promising not only because of their relatively high Curie temperature (T C ) but also due to the possibility of many striking tailored properties for potential applications as diverse as magneto-optical devices, magnetic sensors, bio-sensors and bio-medical applications [32,33].…”
