Abstract

Hybrid materials formed by layers of porphyrins onto ZnO surface show an interesting combination of photonic and gas sensing properties. In this paper, we investigate, with the Kelvin probe technique, the changes of the surface potential of porphyrins coated ZnO nanowires induced by concurrent adsorption of gas and visible light illumination.
