Reference experiments have also been performed in the absence of capping agent to clearly illustrate the effect of capping mechanism. XRD results show broadening of peaks, suggesting formation of the nanometer sized materials and more smaller sizes in the presence of 3-MPA. UV-Vis absorption spectroscopy results show shifting toward lower wavelength, also confirming the formation of nanostructures with smaller dimension. Surface morphology of the prepared material shows the formation of nearly spherical aggregates of nanoclusters.
