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.

简并 Ni 和 (Ga/Zn) 共掺杂 TiO2 纳米复合材料的结构、磁性和光学特性

通过热共沉淀法合成了与 Ni-Ga 和 Ni-Zn 纳米颗粒共掺杂的氧化钛 (TiO2)。分别采用能量色散 X 射线荧光、X 射线衍射、紫外-可见吸收光谱和磁化方法研究元素含量、晶体结构、光学和磁性。目前工作的路线图是探索制备稀磁性半导体 TiO2 的条件。已确定需要对主体掺杂的样品进行氢化以产生铁磁特性。据报道，掺杂非磁性 Ga3+ 和 Zn2+ 离子的效果在氢化 Ni 掺杂的 TiO2 中产生了磁性。使用漫反射光谱 (DRS) 方法研究了未掺杂和主体 TiO2 纳米粉末的一些光学性质。通过流动电子报道和讨论了用 Ni/Ga 共掺杂 TiO2 观察到的更高磁能。
