Resumen

This work presents a study of effect of annealing temperature on optical and structural properties of WO₃ that has been deposited by hot-filament metal oxide deposition (HFMOD). X-ray diffraction shows that the as-deposited WO₃ films present mainly monoclinic crystalline phase. The Raman spectrum 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 enhance and increase their intensity with the annealing temperature. gap can be varied from 2.92 to 3.15 eV by annealing WO₃ from O to 500^°C. The photoluminescence response of the asdeposited film presents two radiative transitions centered at 2.04 and 2.65 eV that are associated to oxygen vacancies.
