Objective: In this study, α-Fe2O3 thin film was formed on a glass substrate to study the impact of adding cold plasma on the self-cleaning and antibacterial properties of the samples. Method: The samples were synthesized using the chemical spray pyrolysis (CSP) method at 450°C. X-ray powder diffraction (XRD), scanning electron microscope (FESEM), energy-dispersive X-ray spectroscopy (EDS), and atomic force microscope were used to investigate the morphological and structural characteristics of α-Fe2O3 thin layers prior to and following plasma injection. Finding: The degree of wettability and antibacterial characteristics of iron oxide (hematite) thin film were evaluated in the presence of gram-negative and gram-positive bacteria prior to and following plasma injection, given the great potential of plasma injection in the surface modification of thin films. Novelty: The findings indicate that exposing plasma to α-Fe2O3thin film produces substantial changes in morphology, self-cleaning, and antibacterial characteristics.

“…39 The smaller primary particles have large surface free energy and tend to agglomerate, coalesce, and grow into larger grains. 17,40 The rotationcoalescence of neighboring grains results in elimination of grain boundaries between them and supposedly grain growth. Therefore, grain growth upon anodization is expected to reduce recombination rate of holes and electrons and subsequently enhance conductivity of the photoelectrode.…”

In searching for a suitable semiconductor material for hydrogen production via photoelectrochemical water splitting, a-Fe 2 O 3 received significant attention as a promising photoanode due to its band gap (;2.1 eV), good stability, low cost, and natural occurrence. a-Fe 2 O 3 thin films were prepared by economic and facile dip coating method and subsequently subjected to an anodic potential of 700 mV versus Ag/AgCl in 1M KOH for different anodization times (1, 10, and 900 min) under illumination. X-ray diffractometry revealed increase in crystallites size from ;31 nm for nanoparticles in pristine state to ;38 and 44 nm after anodization for 1 and 900 min, respectively. A clear positive correlation between anodization time and grain (particle) size was observed from field emission gun scanning electron microscopy and atomic force microscopy (AFM); longer exposure time to anodizing conditions resulted in larger grains. Grain size increased from ;57.9 nm in pristine state to ;153.5 nm after anodization for 900 min. A significant smoothening of the surface with increase in anodization time was evident from AFM analysis.

“…The films have an optical band gap of 2.95–3.02 eV as the Mn doping percentage varies from 8 to 0%. Both antibacterial activity and optical properties of the thin film increases with Mn doping impling that Mn in α-Fe 2 O 3 can be tuned for biobased optoelectronic devices …”

Despite extensive research into novel materials, iron oxides remain fascinating and attract considerable attention because of their versatility, stability, ease of fabrication, low cost, natural abundance, and environmental friendliness. Because of their wealth of magnetic, optical, and electrical properties, iron oxides are particularly multifunctional materials that can be integrated into various devices. In this article, we will discuss the applications of iron oxide thin films in electronics (spintronics devices), energy (batteries and solar cells or photovoltaics), and sensors (gas, humidity, strain, biosensors, and so on). We begin with the most recent forms and fabrication methods for iron oxide thin film, as well as a fundamental understanding of the material. Additionally, the application constraints of these devices are discussed, and the challenges, solutions, and prospects for electronic devices based on iron oxide are outlined.
