Description
Summary:Nanostructured Ag-doped ZnO nanoparticles, and its polymeric nanocomposites (Ag:ZnO/PMMA) were synthesized in the laboratory via free radical polymerization process. The formation of PMMA matrix, its nanocomposites and relative changes in nano structured properties were examined by Fourier transform infrared spectroscopic (FTIR) analysis. Nanohexagonal structure was formed in the PMMA polymeric pattern with the incorporation of Ag:ZnO nano fillers, as examined by surface morphology images. Optical absorption spectra associated with the blue region of visible range and the optimized concentration showed reduced band gap ~2.55 eV which led to increase the p-type conductivity. Increased rate of electron–hole radiative recombination and an enhanced current density ~85.70% were examined. This revealed a significantly improved conductivity of the Ag:ZnO/PMMA nanocomposites. The nano fillers Ag:ZnO have fairly improved the optical absorption, conduction and an enhanced current density of nanocomposites which can be used as electron transport layer in the OLED device fabrication.
