The effect of the calcination temperature on the extinction coefficient and energy loss of TiO2/WO3 nanoparticles synthesized by the sol-gel method

In this paper, titanium dioxide/tungsten trioxide nanoparticles were synthesized by sol–gel method. Oftitanium tetra-chloride was used as a precursor. Obtained nanoparticles at different calcination temperatures wereanalyzed and characterized by X-ray Diffraction (XRD), scanning electron microscope (SEM) and Ultraviolet–visiblespectroscopy (UV-vis) techniques. The effect of calcination temperature on the Extinction Coefficient and energy Lossof nanoparticles has been studied. It is shown that with increasing calcination temperature, Extinction Coefficient andLoss of energy increases.
