摘要：

Microstructural, optical, AC dielectric impedance, and conductivity properties of pure PVA and PVA: NaSe SCF samples doped with various NaSe salt fillers were investigated. The XRD study confirmed the semicrystalline structure of the PoIVA:NaSe SCF samples which explicated the semi-crystalline nature of the pure PoIVA as a matrix. This is related to a strong intermolecular contact among PoIVA chains over intermolecular hydrogen connections. As NaSe salt fillers in the PoIVA matrix increased, bandgap energies decreased. The Urbach energy was also changed with the variation of Mo concentration. The AC dielectric properties were enhanced with the introduction of NaSe salt fillers. As the NaSe salt fillers increase, the DC electrical conductivity parameters decrease. The AC impedance parameters infer that the prepared sample is a potential dielectric candidate. The studied material can be used in electronic and optoelectronic applications, especially CUT-OFF laser filters. (C) 2022 Vietnam National University, Hanoi. Published by Elsevier B.V.
