Ferromagnetic, Optical and Photoluminescence Behavior of Ni-Doped ZnO Thin Films

Aloe vera assisted green synthesis of Ag and Cu co-doped ZnO nanoparticles and a comprehensive analysis of their structural, morphological, optical, electrical and antibacterial properties

“…Among these, ZnO NPs are notable for having a large exciton binding energy, a direct energy band gap between 3.1 and 3.3 eV, and wide band gap semiconductor characteristics [ 6 ]. Their diverse applications into span optoelectronic devices [ 7 , 8 ], biosensors [ 9 ], disease diagnosis [ 10 , 11 ], antibacterial agents [ 12 , 13 ], solar cells [ 14 ], photocatalysis [ 15 ] and energy storage devices [ 16 ] are significant in the current scientific world. Zinc oxide nanoparticles have become highly sought-after in the fields of solar cell and energy storage technologies due to their distinctive properties, which include a wide bandgap, excellent electrical conductivity, and a high surface area.…”

“…Transition metal ion doping into the ZnO lattice (under controlled conditions) has shown to be a flexible way to improve performance for optoelectronics, biomedicine, and electronics applications. Doping with elements such as Ni [ 8 , 54 ], Co [ 9 ], Sn [ 55 ], Al [ 56 ], Ag [ 57 ], Cu [ 7 ], Sr [ 58 ], Mg [ 59 ], Sn [ 60 ] and Mn [ 61 ] have demonstrated significant alterations in the properties of ZnO nanoparticles, opening avenues for advanced applications. Co-doping ZnO NPs with various materials has garnered significant interest in enhancing the efficiency and sustainability of ZnO NPs.…”
