Abstract
By one-step Laser Ablation of a erbium plate dipped in Carboxymethyl cellulose/Polyvinyl alcohol (CMC/PVA ((50/50 wt %) solution, Er2O3NBs were fabricated. The Physical characterization of the produced nanocomposite films were performed via different technique. In addition. The electrical conductivity and dielectric properties for the prepared CMC/PVA/ErO3NPs have been investigated. FT-IR showed rapidly decreased in most peaks intensities after embedded of ErO3, which approve the complexationbetween CMC/PVA and Er2O3 NPs. The values of energygap were decreased by increasing the content of Er2O3NPs in CMC/PVA and increasing the laser ablation duration to 20 min, achieving 3.29 eV and 1.51 eV, respectively. AC results confirms the modification after the incorporation of Er2O3 NPs. The results show that using Er2O3 NPs make improvement in both electrical, thermal, and optical characteristics of the composite.
•CMC/PVA/Er2O3 NPs films well prepared by using PLAL process.•XRD approved the embedding of Er2O3 NPs in CMC/PVA is crystalline structure.•UV–Vis showed the appearing of SPR absorption peak of the embedded Er2O3 NPs.•FE-SEM scans show a clear change confirming the doping of Er2O3 NPs on the surface.•Values of σac′ are increased as ablation time increased at higher frequencies.
