Abstract:
Zinc oxide is recently being used as magnetic semiconductor with introduction of magnetic elements in it. In this work, we report phase pure synthesis of Mg and Ni co-substituted ZnO to explore its structure, optical, magnetic and photo-catalytic properties. X-ray diffraction analysis reveal the formation of hexagonal wurtzite type structure having P63mc space group without any impurity phase. UV-Vis spectrophotometry demonstrate the variation in band gap with addition of Mg and Ni content in ZnO matrix. Magnetic measurements exhibit a clear boosted magnetization in Ni and Mg co-doped compositions with its stable value of band gap corroborating the structural stability and magnetic tuning for its advanced applications in modern day spintronic devices. Photo-catalytic measurements were performed using methyl green degradation demonstrate an enhanced trend of activity in Mg and Ni co-doped compositions.
