WO3 optical band gap energy can be varied from 2.92 to 3.15 eV obtained by transmittance measurements by annealing WO3 from 100 to 500±C. The Raman spectrum of the as-deposited WO3 film shows four intense peaks that are typical Raman peaks of crystalline WO3 (m-phase) that corresponds to the stretching vibrations of the bridging oxygen that are assigned to W-O stretching (º) and W-O bending (±) modes, respectively, which enhanced and increased their intensity with the annealing temperature. 2012 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57025091010 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
