UV–vis spectra and plot of (αhν)2 vs photon energy for Cu-ZnO hybrid nanoparticles. (a) UV–vis spectra of Cu-ZnO hybrid nanoparticles dispersed in different solvents, in comparison to ZnO nanoparticles dispersed in hexane and (b) plot of (αhν)2 vs photon energy for Cu-ZnO hybrid nanoparticles dispersed in different solvents, in comparison to ZnO nanoparticles dispersed in hexane.
