Abstract:
Here, this study is a demonstration of all step solution processed heterojunction light emitting diode (LED) based on a hybrid configuration consisting of Poly(9,9-di-noctylfluorenyl-2,7-diyl) (PFO) thin film deposited on ITO glass substrate followed by grown of n-type ZnO nanorods on top of PFO by a low-temperature chemical aqueous method. Field emission scanning electron microscope (FESEM), X-ray diffraction (XRD), photoluminance spectroscopy (PL) and UV-vis spectroscopy analysis indicated the shape, density, crystallinity and defects level of the ZnO nanorods. As-fabricated organic-inorganic LEDs showed a stable rectifying diode behavior, and it was also observed that the turn-on voltage of the LEDs is depending upon thickness of PFO film optimized by spin coating speed. The broad PL spectrum of ZnO nanorods in the blue and green regions lead to observation of the blue light by a naked eye under forward bias. The results indicate that solution processed hybrid ZnO/polymer LED structure with reasonable electrical properties greatly influences the reduction of processing cost and promising for large area lightening applications.
