Abstract
Organic-inorganic hybrid composite materials have been extensively studied recently. Organic light-emitting devices are energy conversion devices based on electroluminescence. Gold nano-particles have high corrosion-resistance, high melt temperature, and good chemical stability. In this paper, we report an experimental study on gold nano-particles doped in π-conjugated polymers. These composites could be dispersed in solvents and films. We used MEH-PPV as the organic material and gold nano-particles as doping materials. The device had a multilayer structure as ITO/ PEDOT:PSS/MEH-PPV:Au/Mg:Ag. Due to the quantization effect, the nano material could cause the surface plasmon resonance. When the gold nano-particle doped MEH-PPV concentration increased, the absorption spectra intensity at 370 nm from the gold nano-particles was increased. Tunneling current has been found even at very low voltage. The concentration increase enabled efficient fluorescence quench via both energy transfer and photo-induced charge transfer.
