Resumo: Robust evidences are presented that show that the Raman mode close to 250 cm-1 in Sb2Se3 thin films does not belong to this binary compound. A study of the Raman spectrum power dependency revealed the formation of Sb2O3 for high values of power excitation when these measurements are done in normal atmospheric conditions. In order to complement this study, Sb2Se3 thin films were annealed to mimic the thermal conditions of Raman measurements and characterized by X-ray diffraction technique. These measurements showed that the compound Sb2Se3 can be replaced by Sb2O3 under those conditions and a heat-assisted chemical process explains these findings. Furthermore, it is shown what the Raman conditions that are needed for correct measurements to be performed.
