Iron sesquioxide, Fe2O3Iron sesquioxide (Fe2O3), also known as ferric oxide or hematite, is a reddish-brown compound with various applications across industries. In optics, Fe2O3 is often used as a pigment in coatings and materials that require specific absorption or scattering properties. Its optically active properties have also made it a subject of study for photonic and plasmonic applications, particularly in the development of sensors and imaging technologies. Thin films of Fe2O3 have been investigated for use in optoelectronic devices and waveguides. While not a traditional optical material, iron sesquioxide provides specific characteristics beneficial to specialized optical applications and research.
