In this work, pure and different metal ions doped ZnO thin films were obtained by a facile electrochemical deposition process. Different morphologies of ZnO, such as nanoplates, nanoparticles, as well as dense film can be obtained by doping Cu, In, and Al, respectively. Besides, the electrical properties of ZnO were also dependent on the doping ions. In this work, only pure ZnO shows resistive ...

ZnO thin films with significantly reduced band gaps were synthesized by doping N and codoping Al and N at 100 C. All the films were synthesized by radiofrequency magnetron sputtering on F-doped tin-oxide-coated glass. We found that codoped ZnO: (Al,N) thin films exhibited significantly enhanced crystallinity compared with ZnO doped solely with N, ZnO:N, at the same growth conditions. Furthermor...

ZnO is one of the most promising materials since it has a high mechanical and thermal stability, and wide band gap (3.37 eV). Meanwhile, doping with selective elements offers an effective method to enhance and control the electrical and optical properties of ZnO nanostructures, which is crucial for its practical applications. Mg-doped ZnO have considerable interests owing to their unique optica...

A new type of large area metal organic chemical vapor deposition (MOCVD) system for the growth of high quality and large size ZnO materials is introduced. Materials properties of the un-doped, nand p-doped ZnO epi-films grown on sapphire substrates by this MOCVD system are studied by various techniques, including high resolution X-ray diffraction (XRD), UV–Visible optical transmission (OT), pho...

The antibacterial and antibiofilm activity of chemically synthesized pure and Cu doped ZnO nanoparticles against marine biofilm forming bacteria has been reported for the first time. The synthesized nanoparticles were characterized using PXRD, FTIR and SEM which confirmed the formation of phase pure nanostructured zinc oxides. The antibacterial and antibiofilm activities of the synthesized nano...

Gallium doped zinc oxide (GZO) thin films have been prepared by a simple sol–gel spin coating technique. XRD results showed the preferential c-axis orientation of the crystallites and the presence of the wurtzite phase of ZnO. A lowest resistivity of 3.3 × 10−3 cm was obtained for the ZnO film doped with 2 at% of Ga after post-annealing at 500 ◦C for 45 min in a H2 atmosphere. All the films sho...

In this study, a series of 3d transition metal (TM) (Co, Ni and Fe) doped ZnO particles synthesized by simple co-precipitation method. Structural, morphological magnetic properties were investigated to determine correlation between growth process ferromagnetism samples. All samples had hexzagonal würtzite structure slightly shift indexed peaks was observed TM incorporation in ZnO. Although gran...

The nickel modified zinc oxide (ZnO) photocatalysts with nominal composition of Zn1-xNixO (x = 0.0–0.5) were synthesized by wet chemical approach. Optical studies performed using Fourier transformed infrared (FTIR), electronic spectroscopy and X-ray diffraction (XRD) methods. Scanning electron microscopy (SEM) complimented Energy Dispersive (EDX) was used to study the morphology prepared photoc...

The application of nanomaterials has gained considerable momentum in various fields in recent years due to their high reactivity, excellent surface properties and quantum effects in the nanometer range. The properties of zinc oxide (ZnO) vary with its crystallite size or particle size and often nanocrystalline ZnO is seen to exhibit superior physical and chemical properties due to their higher ...

We demonstrate a thermoelectric nanogenerator (NG) made from a single Sb-doped ZnO micro/nanobelt that generates an output power of about 1.94 nW under a temperature difference of 30 K between the two electrodes. A single Sb-doped ZnO microbelt was bonded at its ends on a glass substrate as a NG, which can give an output voltage of 10 mV and an output current of 194 nA. The single Sb-doped ZnO ...
