Investigation of surface plasmon enhanced organic light emitting diode by numerical analysis

In this paper, a numerical analysis that approaches to model localized surface plasmon (LSP) leading to enhance lighting intensity in organic light emitting diode (OLED) is reported. LSP was applied in enhancing signal of Raman Spectroscopy, absorptivity of solar cell and lighting intensity of light emitting diode (LED), etc. It is commonly manufactured from metal nanoparticles, and the enhancement of light emitting is dependent on the size, period and geometry of these nanoparticles. We build a simulation model to obtain optimum parameters which provide a way to assist the research of OLED.
