Abstract
In this paper, pure NiO and vanadium-doped NiO microstructures have been synthesized by adopting a hydrothermal route at a fix temperature of 150 °C. To know the effect of vanadium doping on the structure and morphology of synthesized materials, various characterization techniques were used. Different morphology and shapes have been observed in the SEM analysis which shows that vanadium doping influences the structure of prepared samples. The size of the microstructures decreases with the increase of V doping in NiO. Energy-dispersive X-ray spectroscopy (EDS) confirms the presence of Ni, O, and V in pure and doped samples. XRD analysis described that NiO has a cubic structure. Photoluminescence (PL) results showed few defect-related peaks along with band edge emission, which are crucial for light-emitting diodes. Vibrating sample magnetometry (VSM) studies reveal that these doped NiO particles exhibit ferromagnetic behaviors at room temperature which could be used efficiently in spintronics.
