The inorganic-organic hybrid junction was synthesized on ITO glass substrate,which was consisted of an n-type ZnO nanorods(NRs)grown by low-temperature aqueous chemical growth method and a p-type polyfluorene(PF)organic film fabricated by spin-coating.The experimental results indicate that densely and uniformly distributed ZnO nanorods are successfully grown on the PF layer.The thickness of the PF layer plays a dominant role for the current-voltage(I-V)characteristic of the ZnO NRs/PF inorganic-organic hybrid junction device,and a p-n junction with obviously rectifying behavior is achieved with optimal PF layer thickness.The photoluminescence(PL)spectrum covering the broad visible range was obtained from the n-ZnO nanorods/p-polyfluorene(PF)structure,which was originated from the combination of the PF-related blue emission and the ZnO-related deep level emission.
