- Abstract
In order to create undoped and doped sodium carboxymethyl cellulose/polyvinyl pyrrolidone/polyethylene glycol (CMC/PVP/PEG) blends with, ZnS/V and TBAI, the solution casting technique is used. The structure and microstructure of ZnS/V filler were inspected with Rietveld method. The structure, composition and surface morphologies of prepared blends were explored by X-ray diffraction (XRD), dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM). The fillers have been integrated into the CMC/PVP/PEG structure, as evidenced by XRD, EDS, and SEM analysis. The diffuse reflectance spectroscopy technique was used to determine the linear/nonlinear optical properties. The optical band gaps of undoped blend (direct and indirect) are 4.91 and 4.11 eV, respectively. These values decreased as the blend doped with ZnS/V and TBAI to 3.74 eV/2.63 eV. The effect of ZnS/V and TBAI on the emitted colors from undoped and doped blends was investigated. CIE chromaticity coordinates revealed that all blends emitted blue light under an excitation wavelength of 317 nm. The effect of doping on the AC conductivity, dielectric constant, electrical modulus and energy densities of the CMC/PVP/PEG blend was investigated.
