[en] In this paper, solid films of polyvinyl alcohol (PVA) complexed with different concentration of FeCl₃ have been successfully synthesized. X-ray diffraction showed that a drop in the crystallinity of PVA with FeCl₃. UV-Vis spectra show that FeCl₃ remarkably enhances UV absorption of PVA, indicating a reduction of optical band gap (OBG). This led to the assumption that increased UV absorption can be assigned to an influence of FeCl₃ on PVA synthesis. In addition, OBG study shows decrements in the values of direct band gap and indirect band gap with FeCl₃ content. These results led to conclude that FeCl₃ doped PVA films are good candidates in the packaging community and photovoltaic application.
