Abstract

This study investigates the impact of Dy³⁺ doping in Lithium-Nickel ferrite. Nanoparticles of Dy³⁺ doped Lithium-Nickel ferrite (Li_1.8Ni_0.1Dy_yFe_2-yO₄) with varying concentrations (y = 0.025, 0.05, 0.075, 0.1, 0.125) have been successfully synthesized using the Sol-Gel auto-combustion technique. Li_1.8Ni_0.1Dy_yFe_2-yO₄ ferrite crystallizes in a spinel cubic structure, although the presence of secondary phases is observed. Various characterization tools, including X-ray diffraction for phase investigation, Vibrating sample magnetometry for magnetic properties, Fourier Transform Infrared Spectroscopy for structural analysis, and Ultraviolet–visible spectroscopy for absorption bands, have been employed in this study. The analysis of X-ray diffraction data reveals that the crystallite size falls within the range of 32.79–11.13 nm. Notably the crystallite size determined using both the Debye-Scherrer formula and the Williamson and Hall plot is in close agreement. The Fourier Transform Infrared Spectroscopy pattern of the synthesized ferrite elucidates the asymmetric stretching mode of the spinel transition in Li_1.8Ni_0.1Dy_yFe_2-yO₄. Additionally, the saturation magnetization for Li_1.8Ni_0.1Dy_yFe_2-yO₄ ranges from 13.7778 to 25.5333 emu/gm. The UV–visible spectra analysis reveals decreased optical band gap energy of Lithium-Nickel ferrites after Dy³⁺ doping. Subsequently, the synthesized nanoparticles demonstrate promising antibacterial and antifungal activity, yielding positive results in the conducted tests.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
