Abstract

In this research, a casting method has been used to prepare (PVA-codoped with (Al(NO3)3 and Fe(NO3)3) as trivalent metal ions. The Fe3+-ions with different concentrations (i.e., 0.1, 0.4, 0.8, 4, and 8 wt%) were added to the 5 wt% of Al3+/PVA solution to form a codoped composite film. The as-prepared sample was characterized by FT-IR, X-ray diffraction, optical absorption, electrical properties studies, and optical limiting effect. FTIR results showed the interlinked of Fe3+-ions with the OH group in the PVA matrix. The investigation of (XRD) indicates that the pure PVA and the doped films are semi-crystalline. The optical bandgap of PVA decreases with raising the concentration of Fe3+-ions. The dielectric properties and AC electrical conductivity were studied and dependent on the Fe3+-contents. The analyzed material displayed great performance for the optical limiting for two laser sources of 632.8 and 533 nm. The plots of the field-dependent magnetization measured at room temperature showed a weak room temperature ferromagnetism with the significant paramagnetic components. Consequently, this study has successfully discovered that Fe3+-codoped Al3+/PVA composites are good candidates for use in different electronic, optoelectronic, and CUT-OFF laser device applications.
