Schematic illustration of ZnO NRs/PFO hybrid device on PEDOT:PSS coated flexible plastic.
SEM image of the as grown ZnO NRs on PFO polymer and the inset shows the SEM image after spin coating and followed by soft backing.
Typical RT I-V characteristics of the ZnO NRs/PFO hybrid WLED and the inset show the semilog plot of I-V characteristics.
