“…The value of E g is determined from the intercept of the straight-line portion at the horizontal axis when a = 0. This method is known to be accurate for the estimation of the Eg of ZnO nanostructures [43][44][45]. The relationship of (ahm) 2 and photon energy hm for ZnO nanostructures deposited at different concentrations of Zn 2?…”

Zinc oxide (ZnO) nanostructures were deposited under potentiostatic control on indium tin oxide coated glass substrate from an aqueous solution containing zinc nitrates. Voltammograms were recorded to determine the optimal potential region for the deposition of ZnO. The deposition was carried out at various concentrations of Zn ?2 and constant bath temperature (65°C). The nucleation and growth kinetics at the initial stages of ZnO studied by current transients indicated a 3D island growth (Volmer-Weber). It is characterized by an instantaneous nucleation mechanism followed by diffusion-limited growth. The Mott-Schottky measurements, the flat band potential and the donor density for the ZnO nanostructures were determined. The morphological, structural, and optical properties of the nanostructures have been investigated. Scanning electron microscopy images showed different sizes and morphologies of the nanostructures which depends on the concentrations of Zn ?2 . X-ray diffraction study confirms the wurtzite phase of the ZnO nanostructures with high crystallinity. UV-visible spectra showed a significant optical transmission (up to 90 %), which decreased with Zn 2? concentrations. The energy band gap values have been estimated to be in the range 3.36-3.54 eV.

“…ZnO is known to be an n-type semiconductor with a wide band gap 3.35 eV at room temperature and a large exciton binding energy of about 60 meV [7]. Numerous techniques such as reactive evaporation, sputtering, pulsed laser deposition, sol-gel and spray pyrolysis were used for the growth of undoped and doped ZnO thin films [8][9][10][11][12][13][14][15][16]. It is well established that physical and chemical properties of ZnO can be largely modified upon doping [17][18][19][20][21].…”

Abstract. Neodymium-doped zinc oxide (NZO) thin films were deposited on glass substrates by spray pyrolysis technique. X-ray diffraction patterns have shown that both undoped and Nd-doped ZnO films exhibit the hexagonal wurtzite crystal structure with a preferential orientation along [0 0 2] direction. The effective doping concentration has been determined by Rutherford backscattering measurements showing that the neodymium is not incorporated easily into ZnO host matrix. The surface roughness was shown to increase with Nd doping. NZO films are highly transparent in the visible region. The lowest electrical resistivity value of about 4.0 10 −2 Ω cm was obtained for 1% Nd effective doping.

“…Reports about Fe:ZnO thin films focus mostly on ferromagnetic properties [12][13][14][15][16]. Structural, optical, and electrical properties of Fe:ZnO films are relatively less studied [17][18][19] though it merit deeper understanding. Wide band gap ZnO is well known as a transparent-conducting oxide (TCO), very interesting and promising material for transparent electronics [20].…”

“…Fe:ZnO thin films could be prepared by many techniques such as co-sputtering [13], sol-gel method [14,17], spray pyrolysis method [18], magnetron sputtering [8,10,19], and pulsed laser deposition [21]. Compared with other techniques, spray pyrolysis method has many advantages such as simple apparatus, high deposition rate, good adhesion, good uniformity, and suitability for large area deposition.…”

ZnO thin films doped with iron have been grown by spray pyrolysis technique on glass and fused silica substrates in order to study the effect of substrate material on the structural, optical, and electro-magnetotransport properties of grown layers. The polycrystalline Fe:ZnO films have different growth orientation according to the substrate, though both films are highly transparent in the visible region of wavelength. The sample grown on glass substrate has larger magnetoresistance and lower electron mobility than that on fused silica substrate.
