AFM images of (a) the nanoparticles embedded in the MEH-PPV layer and (b) only the MEH-PPV layer, and (c) the magnified surface morphology of the nanoparticles embedded in MEH-PPV layer. The inset of (c) indicates a cross-sectional analysis of the selected region between two arrows shown in (c). The region between the dashed lines corresponds to the nanoparticle.
Capacitance-voltage curve for a Au/[ nanoparticles embedded in the MEH-PPV layer]/ITO/glass device.
Capacitance-voltage curves for an Al/[ nanoparticles embedded in the MEH-PPV layer]/ITO/ glass device under (a) positive and (b) negative voltages.
Schematic diagrams of the electronic structures corresponding to the operating mechanisms of the charge capturing and the charge storing processes for (a) a Au and (b) an Al/[ nanoparticles embedded in the MEH-PPV layer]/ITO/glass device under a positive bias voltage. The energy levels for the core/shell-type nanoparticles are taken from the literature of Ref. 17, and those for the MEH-PPV layer are taken from Ref. 18.
