Ni-NWs have emerged as a viable material due to their electrical, thermal, and magnetic properties.In present research work Ni-NWs are purchased from Plasma Chem (Germany) with diameter in the range 200 to 300 nm. Ni-NWs are irradiated by copper ions beam irradiation to study the changes in properties. Ni-NWs are exposed to copper ions beam of energies 30keV, 40keV and 50keV and fluence was 1 X 1015 ions/cm2 at room temperature. Radiational effects of copper ions beam of various energies on the Ni-NWs structure and morphology are studied by characterizing the sample using X-Ray Diffraction and Transmission Electron Microscopy (TEM) techniques. XRD results show the characteristic peaks of Ni-NWs having cubic phase. Grain sizes were calculated by using Scherrer’s equation. Calculations show that Crystallite size was increased up to 40 KeV and then started to be decreasing. Dislocation density and lattice strain is also calculated which showed opposite behavior compared to crystallite size. Dislocation density and lattice strain initially decreased and started increasing after 40 KeV. TEM images revealed that radius of Ni-NWs reduced by copper ions beams irradiation. Reduction in radius is observed due to lose of atom because of copper ions beam irradiations. This research highlights the changes in properties of Ni-NWs due to copper ions beam irradiations for its implementation as transparent electrodes in optoelectronic devices. Moreover, we studied the legal implications of use of nanowires in nanodevices or optoelectronic devices such as environmental and health liability, ethical and data privacy considerations.
