Title : Optical property enhancement of Zn-doped BaNi ferrite for advanced nanotechnology applications
Abstract:
This study investigates the effects of Zn2+ ion doping on the vibrational spectroscopic characteristics and optical properties of BaNi2−xZnxFe16O27 ferrite. The formation of a W-type hexaferrite structure was confirmed through powder X-ray diffraction analysis. The crystallite size was determined to be in the range of 35–37 nm, increasing with higher Zn2+ content. Infrared spectra analysis revealed two distinct vibration bands, ν1 and ν2, corresponding to tetrahedral and octahedral sites within the ferrite structure, respectively. The addition of Zn ions resulted in changes in the optical characteristics of the material, including increased absorption capacity, decreased reflectance, and altered refractive index. The threshold frequency νth, associated with electronic transitions, increased with higher Zn ion concentration. Fourier transform infrared (FT-IR) spectra were used to determine the cation distribution within the mixed ferrite, based on ionic radii. This research provides insights into the optical properties of doped ferrites, with implications for nanotechnology applications in fields such as optoelectronics, photonics, and sensors. The enhanced optical properties of Zn-doped BaNi ferrite have potential applications in various areas of nanotechnology: Optoelectronics: The improved optical properties can be used to develop more efficient photodetectors, LEDs, and optical sensors.
Solar Cells: The increased absorption capacity and reduced reflectance make Zn-doped BaNi ferrite suitable for improving the efficiency of solar cells.
Data Storage: Zn-doped BaNi ferrite can be used in magneto-optical storage devices for data storage applications.
Display Technologies: The enhanced optical characteristics contribute to the development of advanced display technologies like high-resolution displays, flexible displays, and transparent displays.

These applications demonstrate the potential of Zn-doped BaNi ferrite in various fields of nanotechnology, enabling advancements in optoelectronics, photonics, solar energy, sensing, data storage, display technologies, and nanophotonics.
