The interplay between photosensitivity and chemical sensitivity can give rise to a number of properties that can extend the sensitivity in each separate context. Here we illustrate how the sensitivity to visble light of porphyrins coated ZnO nanorods can modify the gas detection enhancing the sensitivity in particular towards electron donor species.
