Synthesis and Characterization of Ni Doped ZnO Nanoparticles

Abstract

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.

Effect of Transition Metal Doping on the Structural, Optical, Thermal Properties, and Antimicrobial Activity of Zinc Oxide Nanoparticles

“…No signals of the metallic Zn are detected by XRD. However, there is no peak attributed to Ni, suggesting that the Ni +2 ion may be doped into ZnO 17 . It can be concluded from the results that incorporation of Co and Ni into ZnO lattice enhances crystalline quality.…”

Effect of calcination temperature on the structural, optical and magnetic properties of pure and Fe-doped ZnO nanoparticles

“…In the past few years, scientists have investigated the effect of ZnO nanoparticles doping with transition metals, such as Fe, Co, Ni and Mn [8][9][10][11][12][13][14][15][16][17][18][19][20]. Numerous theoretical explanations that have been proposed revealed that on doping ZnO nanoparticles with these transition elements results in dramatic changes in various luminescent and magnetic properties.…”

Biosynthesis, characterisation and antimicrobial activity of zinc oxide and nickel doped zinc oxide nanoparticles using Euphorbia abyssinica bark extract

“…The diffraction peak of each sample was strong, sharp and narrow that indicates the good crystalline nature of biosynthesised ZnO and Ni doped ZnO NPs [40]. The size of the particles (Table 4) was found to be in the range of the nanoparticle material size of 1 to 100 nm [32,41,42]. Lattice constants a, b, and c, inter planar angle and unit cell volumes were calculated by using Bragg's equation, λ = 2dsinθ and Lattice geometry equation [36].…”
