This work demonstrated an in-depth investigation of the effect of surface doping by three different polymers on the synthesis of zinc ferrite nanostructures by a thermal method. The zinc ferrites were doped with 20% concentration by mass of Polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP) and ...
Improving the optical and dielectric characteristics of PVA/PVP/PEG/ZnWO4/CdS blends TheEgvalues decreased irregularly as the undoped blend was loaded with (1-x)ZnWO4/x CdS samples.Adding (1-x)ZnWO4/x CdS improved the蟽optvalue of the blend......
In this paper, the effect of titanium oxide nanoparticles on optical properties for (PVA-PEG-PVP) blend has been studied. The titanium oxide nanoparticles was added to the (PVA-PEG-PVP) blend for different weight percentages are (2, 4, 6, 8) wt.%. The optical properties were measured in...
