“…PVA has been doped with dopant such as polymers, metal salts, and ions to obtain desired properties [6][7]. Many papers reported studies on structural and optical properties of additive doped PVA systems [8][9][10][11][12][13]. It is reported to be a nice matrix material to accept metal nanoparticles as has been observed that Co nanoparticles can be embedded in the matrix of PVA to display magnetic properties [8,14]; and with gold nanoparticles captured in the PVA matrix system can provide characteristic optical properties [15].…”

The pristine poly(vinyl alcohol) and CuS nanoparticles with different concentrations (1 %-10 %) doped PVA films were prepared by solution casting method. The CuS nanoparticles were prepared by chemical precipitation; and XRD studies confirmed the formation of pure CuS nanoparticles with average size of 18 nm. The optical properties of pristine as well as doped PVA films were evaluated using UV-VIS-NIR spectroscopy. UV-VIS-NIR spectrum of CuS nanoparticles showed LSPR band in NIR region. The optical properties like absorption coefficient, bandgaps, high frequency refractive index, and metallization criterion have been evaluated; both the direct and indirect band gaps decreased in case of doped PVA films; and the results and the features are discussed.
