Abstract
Titanium oxide (TiO2) codoped with Ni-Ga and Ni-Zn nanoparticles were synthesized by the thermal co-precipitation method. The energy-dispersive x‐ray fluorescence, X‐Ray Diffraction, UV–visible absorption spectroscopy, and magnetization methods were performed to study the elemental content, crystalline structure, optical and magnetic properties, respectively. The roadmap of the present work is to explore the conditions of fabrication of dilute magnetic semiconductors, TiO2. It was established that the hydrogenation of the host-doped samples is required to create ferromagnetic properties. It was reported that the effect of doping with non-magnetic Ga3+ and Zn2+ ions created magnetic properties in the hydrogenated Ni-doped TiO2. Some optical properties of undoped and host TiO2 nanopowders were investigated using the diffuse reflectance spectroscopy (DRS) method. The higher magnetic energy observed with Ni/Ga-co-doped TiO2 was reported and discussed by itinerant electrons.
