This report presents the preparation and spectroscopic properties of rGO: ZnO composite nanostructures. The reduced graphene oxide (rGO) and rGO:ZnO composite structures were prepared through modified Hummer’s and solution precipitation techniques, respectively. The decoration of star like ZnO nanostructures on rGO surface was identified through transmission electron microscopy (TEM) analysis. Raman spectral measurements revealed the co-existence of vibrational modes of ZnO and rGO which confirmed the formation of composites nanostructures. The absorption spectra of ZnO hybrid and rGO nanostructures exhibited bands at 370 and 261 nm which were attributed to the free excitonic absorption of ZnO and rGO absorption band, respectively.
