Structural and optical properties of iron oxide α-Fe2O3 nanowires prepared by hydrothermal method

The most stable iron oxide is Fe2O3 (hematite),Which is environmentally friendly. In our paper, we successfully synthesized Hematite1D (Fe2O3) using chemical methods such as co precipitation, heating, and hydrothermal methods. XRD, SEM, and UV-VIS and PL were used to investigate the structure, morphology and optical characteristics respectively of the sample that has been synthesized. According to XRD all maxima are aligned with the peaks that are indicative of the hematite α-Fe2O3 phase, the analyzed materials are α-Fe2O3 with a rhombohedra crystal structure. Hematite is thoroughly researched and is of special interest in technical applications such Catalysts, sensors, environmental pollutant cleanup agents, electrode materials, biomedical materials, and magnetic materials are examples of such materials. Nanowires diameters of 40 - 50 nm and lengths of tens of micrometers and grow in the [110] directions. In the UV-VIS, the sample’s Visible-Light Absorption has a band-gap of 1.9 eV; PL photoluminescence emission spectra show a significant correlation with standard α-Fe2O3.
