Bi2O3 nanoparticles have also redrawn attention due to their excellent properties, mostly as optoelectronic material. Here, we report the room-temperature biosynthesis of Bi2O3 nanoparticles in a size range of 5-8 nm by extra-cellularly challenging the plant pathogenic fungus-Fusarium oxysporum with the bismuth nitrate as precursor. The as-synthesized particle-surfaces are inherently functionalized by a robust layer of proteins which provides them very good stability in the aqueous medium. Structural investigation using selected area electron diffraction, high resolution transmission electron microscopy and powder XRD shows that particles are almost perfectly single crystalline and primarily crystallize in alpha-phase with monoclinic structure.</p>10aBiosynthesis10afungi10aHigh Refractive Index10aHigh Resolution TEM10aNanoparticles1 aUddin, Imran1 aAdyanthaya, Suguna, D.1 aSyed, Asad1 aSelvaraj, K.1 aAhmad, Absar1 aPoddar, Pankaj  uhttps://library.ncl.res.in/content/structure-and-microbial-synthesis-sub-10-nm-bi2o3-nanocrystals-0
