Optical absorption spectra showing the tunability of LSPR of Au–ZnO nanocomposites with increase in annealing temperatures. Inset shows (●) decrease in bandgap of ZnO matrix and shift in LSPR (∗) peak position of Au NPs, with increase in annealing temperature.
XRD spectra showing the structural evolution of Au–ZnO nanocomposite film with increase in annealing temperature.
TEM image of annealed samples showing formation of ZnO nanorods [(a)–(c)] after annealing. (d) shows the HRTEM image of the interface of ZnO nanorod and Au nanoparticles.
Raman spectra of pristine film and film supported on Au–ZnO nanocomposites. This clearly indicates the enhancement in intensity of Raman modes in case of film supported by Au–ZnO nanocomposite.
