Description
Summary:PVA/CMC blend loaded with Zn 0.9 V 0.1 S prepared at different temperatures (T = 200, 300, 400 or 500 °C) were synthesized utilizing solid state reaction and casting methods. Applying Rietveld method, the cell parameter, the crystallite size, and the lattice microstrain of the nanofiller Zn 0.9 V 0.1 S were determined at the various preparation temperatures. The elemental analysis and the distribution of the nanofillers over the blend’s matrix were investigated using X-ray diffraction, SEM and FTIR techniques. The influence of ZnS/V doping on the thermal stability of PVA/CMC was explored using thermogravimetric analysis technique. The optical features for the pure and doped PVA/CMC polymer blends with ZnS/V were explored using diffused reflectance technique. The direct and indirect E g values for PVA/CMC are 5.79 and 5.03 eV, respectively. Upon loading, E g decreased nonmonotonically with T, reaching lowest values (4.51, 2.43) eV for nanofiller prepared at T = 200 °C. The consequences of ZnS/V doping on the fluorescence intensity and emitted colors from different blends were explored. The obtained results are significant for designing novel organic/inorganic polymer blend for emerging technologies.
