This paper discerns key ideas and themes of the possibility of growing Ni doped ZnO nanoparticles by electrochemical method. The purpose is to study the growth mechanism and to optimize the parameters of this method. Upon successful synthesizing the samples, they were characterized using various techniques. XRD, SEM, FTIR, photoluminescence spectroscopy together with the measured optical parameters obtained from UV-VIS absorption testing were analyzed. The X-ray diffraction (XRD) was measured by using a Bruker D8 Advance X-ray diffractometer with CuK α radiation. The surface morphology was investigated using an 'EVO LS 15' scanning electron microscope. The FTIR absorption spectra were recorded on a Perkin-Elmer GX FTIR system. The PL spectra were collected on a Jobin Yvon-Horiba Triax 190 spectrometer with a spectral resolution of 0.3 nm. UV-VIS absorption spectrum was recorded by using a UV-VIS spectrophotometer in the photon wavelength range between 300 and 600 nm. XRD pattern reveals that the polycrystalline of hexagonal wurtzite structure and the average size of the particles were estimated to be approximately 61 nm, which conform the nanoparticle. The FTIR result shows the stretching vibration of the Zn-O bond in Ni doped ZnO nanoparticles. There is a green emission peak centered at about 384 nm in the PL behavior. The band edge is shifted to the lower energy side of the Ni doped ZnO nanoparticle. Analyzing the results of various types of characterizations, it has been assessed that Ni doped ZnO nanoparticles was successfully synthesized.

“…Different physical or chemical synthetic approaches have been developed to produce nano-sized ZnO particles including thermal decomposition, thermolysis [13], chemical vapor deposition, sol-gel [14,15], spray pyrolysis, precipitation [16][17][18][19][20] vapor phase oxidation [21], thermal vapor transport, condensation [22] and hydrothermal [23,24]. Generally, these preparation methods involve complex procedures, sophisticated equipment and rigorous experimental conditions.…”

“…Previous works have demonstrated the influence of Co 2+ and Ni 2+ ion doping on the optical properties of semiconducting oxides, providing the formation of multi-emission centres in the final materials, and promoting a chargetransfer state just below the band-gap energy [17][18][19]. The origin of the visible emission in zinc oxide remains difficult for separating the produced emissions by different types of defects.…”

Rapid synthesis of CO, NI CO-doped ZnO nanoparticles: Optical and electrochemical properties, Journal of Solid State Chemistry, http://dx. AbstractWe report for the first time a rapid preparation of Zn 1-2x Co x Ni x O nanoparticles via a versatile and environmentally friendly route, microwave-assisted hydrothermal (MAH) method. The Co, Ni co-doped ZnO nanoparticles present an effect on photoluminescence and electrochemical properties, exhibiting excellent electrocatalytic performance compared to undoped ZnO sample. Photoluminescence spectroscopy measurements indicated the reduction of the green-orange-red visible emission region after adding Co and Ni ions, revealing the formation of alternative pathways for the generated recombination. The presence of these metallic ions into ZnO creates different defects, contributing to a local structural disorder, as revealed by Raman spectra.Electrochemical experiments revealed that the electrocatalytic oxidation of dopamine on ZnO attached to multi-walled carbon nanotubes improved significantly in the Co, Ni codoped ZnO samples when compared to pure ZnO.
