“…As we can see, the value of the average transmission of spray Zn 1-x Ni x O thin films is about 92% in the visible region. But for these doping levels x, the region of the absorption edge was located between 361 and 379 nm in comparison with others which are found at 355 and 370 nm [33]. It is related region between of the valence band and the conduction band.…”

The effect of Ni doping on structural, optical and electrical properties of deposited Zn1-xNixO thin films on glass substrate by spray pyrolysis technique has been studied. The main objective of this research is to study the change of the physical and optical properties of Zn1-xNixO thin films that are fabricant to semiconductor with different doping levels x. These levels are 0 at.%, 2 at.%, 4 at.%, 8 at.% and 12 at.%. The transmission spectra show that the Zn1-xNixO thin films have a good optical transparency in the visible region from 88 to 95%. The optical gap energy of the Zn1-xNixO thin films varied between 3.25 and 3.35 eV. The urbach energy varied between 65 and 230 meV. However, the Zn0.88Ni0.12O thin films have many defects with maximum value of urbach energy. The Zn0.88Ni0.12O thin films have minimum value of optical gap energy. The Zn0.88Ni0.12O thin films have maximum value of the electrical conductivity which is 9.40 (Ω.cm)-1 . The average electrical conductivity of our films is about (7.52 (Ω.cm)-1 ). XRD patterns of the Zn1- xNixO thin films indicate that films are polycrystalline with hexagonal wurtzite structure.

“…There are many reports for Ni doped ZnO thin films deposition and characterization, such as by spin coating (Yildiz et al, 2011), sol-gel immersion (Ismail et al, 2018), magnetron sputtering (Bayram et al, 2019) and spray pyrolysis technique (Ali et al, 2020;Owoeye et al, 2019;khalidi et al, 2019;_ Iskendero glu and Güney, 2017;Rouchdi et al, 2017;Rajeh et al, 2016). Most of the cases, electrical properties of Ni:ZnO thin films are found inconsistent with Ni doping concentration and the optical properties such as transmittance and band gap are incoherent with Ni doping.…”

Nano-fiber structure of ZnO and Ni doped ZnO (Ni:ZnO) transparent thin films have been deposited on glass substrate at 350 C at an ambient atmosphere via spray pyrolysis technique. The structural, surface morphological and opto-electrical properties of ZnO and Ni doped ZnO thin films have been investigated. The XRD patterns show that the films are of polycrystalline in nature having preferential orientation (0 0 2) plane for ZnO changes to (1 0 1) by Ni doping in ZnO matrix. Optical study exhibits red shifting in band gap energy with Ni doping due to spd hybridization and display high absorption coefficient of the order of 10 7 m À1 . The photoluminescence (PL) spectra indicate blue emissions in all samples. Electrical measurement confirms the resistivity of the film decreases remarkably with Ni doping and electrical transport is mainly thermally activated. From Hall Effect study, it is confirmed that all the samples are n-type having carrier concentration of the order of 10 18 cm À3 . Both mobility and carrier concentrations of the films became higher than ZnO sample with the increase of Ni concentration.

“…Deposition of ZnO thin films has been undertaken via several methods such as sputtering [ 3 ], pulsed vapour deposition [ 4 ], spray pyrolysis [ 5 ] and chemical vapour deposition (CVD) [ 6 , 7 , 8 ]. The advantage of using solution-based methods such as aerosol-assisted CVD is that precursors only have to be soluble, which therefore allows for a greater range of precursors to ZnO.…”

Synthetic and Structural Studies of Ethyl Zinc β-Amidoenoates and β-Ketoiminates

A set of heteroleptic ethyl zinc β-amidoenoates (1, 2) and β-ketoiminates (3) of the form [LZnEt]2 with varying steric bulk have been synthesised via the reaction of diethylzinc with β-aminoenoate ligands HL1 and HL2 and β-ketoimine HL3. These complexes have been characterised via 1H and 13C NMR, mass spectrometry and single-crystal X-ray diffraction, which unambiguously determined all three structures as dimeric species in the solid state. We observe the unusual dimerisation of 1 and 2 through coordination of the central zinc atom to the methine carbon of the second monomer, which gives these complexes high reactivity. The thermal properties of complex 3 are explored via thermal gravimetric analysis (TGA), to investigate their potential as single-source precursors to zinc oxide, which shows that 3 has a significantly lower decomposition temperature as compared to its bis-ligated counterpart [Zn(L3)2], which gives 3 promise as a single-source precursor to zinc oxide.
