Abstract
Nickel-doped cadmium zinc borate glass of various nickel oxide content was prepared as xNiO–20ZnO–60B2 O3 –(20-x) CdO (0≤x≤5 mol %), by the melt quenching method based on nano metal oxides. Both the zinc oxide nanoparticles (ZnO NPs) and cadmium oxide nanoparticles (CdO NPs) were prepared via the solution–combustion technique. Nickel oxide nanoparticles (NiO NPs) was synthesized by the combustion of Ni(OH)2 and boron oxide nanoparticles (B2 O3 NPs)was synthesized by the solid-state reaction method. The amorphous nature of these types of glass was confirmed using X-ray diffraction analysis (XRD). The morphology of nano-metal oxides was investigated via the scanning electron microscope (SEM). SEM imaging showed that the NiO NPs had a semi-spherical morphology, and that their average particle size was 22.17 nm. The Fourier-transform infrared spectroscopy’s (FTIR) spectral analysis was used to identify the structural units of these types of glass via deconvolution, in terms of multi-Gaussian fitting. Results proved that Ni 4+ plays an important role and a key to improve the formation of the BO4 network units. Finally, the high thermal stability and glass transition temperature of the prepared glass samples were increased by increasing the loading of NiO NPs from 0.0 mol % - 5.0 7k = mol % and this was established by using DTA.

Nanotechnology has been established as a simple and modern technology to improve the quality of various products, with strong emphasis on diverse applications, including water treatment and others in the petrochemical industry, medicine, catalysis, and energy
Sallam et al [22] studied the physical properties and radiation shielding parameters of bismuth borate glasses doped 0.7 % of Cu, Co, Ni transition metals Cu, Co, Ni and the results showed that both band gap and electronegativity decreased by the addition of these transition metals
Glass Fabrication and its Characterization The assembled glass samples were fabricated via the melt quenching method as per the procedure discussed by El-Sharkawy et al [8].These were investigated by XRD and FTIR and their thermal stability was estimated
Summary
Nanotechnology has been established as a simple and modern technology to improve the quality of various products, with strong emphasis on diverse applications, including water treatment and others in the petrochemical industry, medicine, catalysis, and energy. The demand for the synthesis of metal oxides in nano form has increased, because of their unique properties, as well as their high efficiency during industrial applications, such as glass fabrication. Glass fabricated from nano metal oxides has great importance, because it is used in many fields, such as healthcare, the nuclear industry and other fields [1,2]. Nickel oxide in the form of nanoparticles is an important type of oxide, because it is used in the anode layer of solid oxide fuel cells, ceramic structures, cathodes for lithium ion micro. The influence of nickel oxide NPs on the structure and thermal characteristics of the formed glass samples has been established
