Abstract

The silver tungstate/cobalt phthalocyanine nanocomposite (Ag₂WO₄/CoPc was prepared by the simple solvent evaporation method. The as-synthesized nanocomposite was characterized by thermo gravimetric and differential thermal analysis, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, photoluminescence spectroscopy and Raman spectroscopy. The structural characterization confirms the formation of the Ag₂WO₄/CoPc nanocomposite. The ultraviolet-visible spectrum for the Ag₂WO₄/CoPc nanocomposite shows extended visible absorption in the wavelength range 670-735nm. Photoluminescence spectrum of the nanocomposite shows large intensity and violet-blue emission when excited with near-ultraviolet light. The present study suggests that the synthesized Ag₂WO₄/CoPc nanocomposite can be a promising material for constructing light emitting diodes, solar cells and optoelectronic devices.
