摘要

In this present work, the samples of poly(vinyl chloride) blended with organic material (domperidone) and doped with many different nanoparticles (cobalt, nickel, and chromium oxides) have been made by method of casting. Thin films were formed with 25 mg of organic material (DOMP) blended with 6 g of PVC and 1% wt. of three nanoparticles, Co₃O₄, NiO, and Cr₂O₃, to dope PVC. The novelty reported is in the design of new PVC nanocomposites that enhance the creation of an anti-reflective layer, providing high absorption for use in optoelectronic applications, as demonstrated in the results. The optoelectronic characteristics of the PVC films nanocomposites were studied depending on the observed spectroscopic data. where, an increase in free carriers of the effective mass \(\:\left(\frac{\varvec{N}}{{\varvec{m}}^{\varvec{*}}}\right)\) from 0.752 × 10⁶¹ to 3.306 × 10⁶¹ (kg. m³)⁻¹, and the high-frequency dielectric constant \(\:{(\varvec{ \varepsilon}}_{\varvec{\infty\:}})\) from 3.0367 to 10.0077, which can be calculated from the Spitzer-Fan model. The single oscillator energy \(\:{(E}_{o})\) were increased from 1.587 to 6.794 eV, dispersion energy \(\:{(E}_{d})\:\) from 11.775 to 43.499 eV, which can be calculated from Wemple-Di-Domenico model. The static refractive index (n_o) where grown from 1.7426 to 3.1635, and the values of average oscillator strength (S_o) from 0.0189 × 10¹⁴ to 1.556 × 10¹⁴ m^− 2, while the oscillator wavelength (λ_o) boosted from 209.76 to 325.40 nm, which can be calculated from the Sellmeier formula. Those parameters were increased with the addition of these nanoparticles to the matrix of PVC. In addition, the tangent loss factor (tan δ), surface energy loss (SELF), and volume energy loss (VELF) had very few values when adding these nanoparticles. These thin films of PVC were widely used in many advanced equipment in optoelectronic applications.
