Nanostructured blends of inorganic and organic materials could unwind unique properties boost performance over each individual constituent. We demonstrate here a hybrid photodetector containing ZnO functionalized oligo(p-phenylenevinylene), which was deposited electrochemically onto an electrode. XRD results reveal that the conjugates formed are lamellar in nature. As photodetectors, room-temperature responsivity as high 0.2 AW–1 at 330 nm with bias −20 V, maximum external quantum efficiency 75% V 100 times increase light current upon UV illumination 325 nm, have been observed. These values perpetrate future high-performance be cost-effective environmentally benign.
