| description | Polymeric nanocomposites were reported to enhance the barrier properties and lifetime of organic solar cells. In this investigation, we are reporting the development of one such nanocomposites by dispersing the lithium zirconate (Li2ZrO3) nanoparticles in polyvinyl alcohol (PVA) matrix. It was found that the incorporation of Li2ZrO3 nanoparticles has not affected the transparency of the PVA matrix in the visible region at the same time it generates fluorescence emission. The emission intensity increases with the nanoparticles concentration. Similarly microwave irradiation also does not show any transmittance peaks in the visible region even though it had a positive effect in the UV region. The dielectric properties (dielectric constant and dielectric loss) of PVA/Li2ZrO3 nanocomposites increase with increase in the nanoparticles concentration, while it decreases with an increase in frequency. The alternating current conductivity increases with the increase in filler loading and frequency. The dissipation factor also increases with nanoparticles addition and decreases with frequency. |
