Arenas-Alatorre Física, Astronomía y Matemáticas Micro Bismuth oxide Thermal oxidation Raman spectroscopy Bismuth nano-sized particles were prepared by the chemical reduction method. These particles were characterized by HR-TEM, X-Ray Diffraction and Micro-Raman Spectroscopy. In order to obtain bismuth oxide, the as-obtained bismuth nano-particles were thermally treated in air at various temperatures in the range 100-750 0C during 30 min. The thermally treated samples were studied by Micro-Raman Spectroscopy. Additionally, information on the chemical composition and morphology was obtained by Energy Dispersive Spectroscopy and Scanning Electron Microscopy, respectively. Results show that bismuth nano-particles were oxidized at 100 oC and transformed into three of the five phases of Bi2O3 reported in literature; the obtained phase depends on the annealing temperature. The β-Bi2O3 phase was obtained for 200-300 0C, α-Bi2O3 for 400-600 0C and finally γ-Bi2O3 for 700-750 0C. 2005 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94218302 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
