Linear and Non-linear optical parameters of Copper Chloride doped Poly (Vinyl Alcohol) for Optoelectronic Applications

Abstract

Poly (Vinyl Alcohol)/Copper Chloride (PVA/CuCl and 20 wt% of CuCl 2 . UV-Vis spectrum of these composites is investigated in the range of 200 spectrum of PVA showed an absorption band at 278.18 nm and a small shoulder at 313.09 nm and are assigned to  * transition, respectively. On the other hand, the spectra of the PVA/CuCl resonance (SPR) band in the visible band at 778.07 nm. Moreover, it is observed that, the absorption edge of composite samples is red shifted. Also, pure PVA showed an which decreased to 3.48 and 3.92 eV after CuCl also observed that nonlinear optical parameters such as thi refractive index (n 2 ) are influenced by CuCl These results are very encouraging for possible applications constant ( ' ), dielectric loss ( '' ) and photoconductivity have been investigated

Enhanced dielectric properties of polyvinyl alcohol doped with ZrC Nanoparticles

“…As compared to conventional dielectrics such as ceramics and polymers are extensively being employed as dielectric substances as polymers display better characteristics, like relatively elevated electric break downfield, processing simplicity, mechanical flexibility etc. Moreover, their characteristics may be modified by incorporating inorganic substances into it [3].PVA is a linear polymer that possesses good optical characteristics, biodegradability, biocompatibility, and nontoxicity, and consequently can be extensively utilized in a variety of field's water soluble, good optical transmission, noncorrosive and has excellent ability for film forming [4].PVA is a semicrystalline and its crystalline index depends on the synthetic method and physical aging [5].In PVA, hydrogen bonding presence between hydroxyl groups is extremely significant for its elevated water solubility and elevated crystal modulus. Normally PVA is a poor electrical conductivity it can become conductor when it is added with other polymer.…”
