Abstract:
In this study, we observed that the electric property of PEDOT:PSS was affected by LSPR effect. LSPR effect was generated by nano gold particles that embedded in PEDOT:PSS films. The high-intensity electric field of LSPR enhances the mobility of carriers. In order to observe this phenomenon, we made some devices. The devices under measurement were composed of ITO glass, thin PEDOT:PSS film, nano gold particles and an Al electrode. In our study, the effect of the devices that were doped with different density of gold nano particles was measured. The higher density of gold nano particles made the lower total resistance of device. The different wavelengths of incident light also made the total resistance of device different. Through those experiments, we validated that the change of electric property of PEDOT:PSS was caused by the LSPR effect from nano gold particles.
