“…Many scientists have reported that polymer nanocomposites ofPVA and PEGhave attracted more attention due to their optical properties and theability to produce hydroxyl group which leads to optical nonlinearity [6][7][8][9][10]. In this article the synthesis, characteristics and third order NLO properties of silicon/PVA-PEG nanocomposites are presented.…”

Si/PVA-PEG polymer nanocomposites wereprepared by solvent casting method. XRD studies revealed the encapsulation of silicon in polymer matrix. Further crystalline behaviour of silicon in the polymer nanocomposites has been investigated. The size and morphological structure have been analysed with SEM. SEM showed the formation of homogeneous between PVA and PEG. FTIR confirmed the presence of silicon and various vibrational bonding natures. Band gap and refractive index of composites have been calculated from optical studies. Z-Scan analysis has been carried out at 532 nm which reveals optical non linearity of Si/PVA-PEG.

Optical characteristics of polyvinyl alcohol/Safranin O dye (PVA/SO) thin films prepared by casting technique have been examined. Compositions and crystalline features of PVA/SO thin films are investigated with X-Ray Diffraction analyses. Ultraviolet–Visible spectroscopy has been utilized to measure the absorption and transmission optical properties of the thin films through the wavelength range 300-900 nm. Two regions can be recognized in absorption coefficient related to the direct band gaps, which are about 3.93 eV of the fundamental energy gap and 2.11eV of the onset gap. The theoretical WempleDiDomenico model has been performed to quantify the static refractive index n and the dispersion energy in addition to the oscillation energy (Eo). The results reveal that the data of the refractive index dispersion in this model obeyed the single oscillator, which is used to deduce the dispersion and the high frequency dielectric constant. In the examined wavelength range, it has been investigated the complex dielectric constant of PVA/SO dye thin films. The ratio of the carrier concentration to the effective mass has been estimated. Oscillation energy values have been examined in this study by describing the expression Eo ≈ Eg and checking the Wemple-DiDomenico model. PVA/SO thin films have interesting physical properties for solar cell applications.
