“…Wemple and DiDomenico’s single oscillator model simplifies calculating refractive index by estimating key material parameters like oscillator and dispersion energies [ 59 ]. Accordingly, the refractive dispersion of a material can be attributed to the contributions of its single-oscillator energy ( E 0 ) and dispersion energy ( E d ), both of which are determined within the framework of their single-oscillator model [ 60 ].

The optical properties of polyvinylidene fluoride (PVDF) polymer nanocomposite films incorporating SrTiO3/carbon nanotubes (CNTs) as nanofillers are investigated. PVDF/SrTiO3/CNTs films were prepared by the solution casting technique. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) analyses confirmed the incorporation of SrTiO3/CNTs into the PVDF matrix. The addition of nanofillers influenced the crystalline structure, morphology, and optical properties of the films. SEM images showed spherulite morphology, which is a spherical aggregate of crystalline polymer chains. The addition of a SrTiO3/CNTs nanofiller modified the polymer’s electronic structure, causing a variation in the energy gap. The addition of SrTiO3/CNTs at 0.1 wt% increased the band gap, refractive index, and nonlinear optical properties of the PVDF films. These improvements indicate the potential of these nanocomposite films in optoelectronic applications such as solar cells, image sensors, and organic light-emitting diodes.

CoxZn1-xO (x = 0.00, 0.04, 0.08 and 0.10) thin films were sprayed pyrolysis onto ordinary glass substrates. The micro Raman spectroscopy revealed the presence of wurtzite structure in all films. The UV-Vis investigation showed good optical transmittance in the visible region with the increase in the absorption bands related to internal Co+2 d-d transitions over Co concentration. The optical gap energy decreased by 0.34 eV as Co doping increased, contrary to Urbach energy which increased by 230 meV. The SEM observation indicated obvious modification in the morphology of the films. M-lines spectroscopy measured the ordinary refractive index which was found to increase by 0.0156 as the Co doping increased. Cobalt doping provoked the extinction of light coupling and propagation in the films manifested as an increase in full width at the half maximum of the guided peaks and a decrease in the reflected intensity. This was due to the increase in the extinction coefficient measured by UV-Vis spectroscopy.
