Noble metals, especially Ag and Au nanostructures, have unique and adjustable optical attributes in terms of surface plasmon resonance. In this research, the effect of Ag and Au nanoparticles with spherical and rod shapes on the light extraction efficiency and the FWHM of OLED structures was investigated using the finite difference time domain (FDTD) method. The simulation results displayed that by changing the shape and size of Ag and Au nanostructures, the emission wavelength can be adjusted, and the FWHM can be reduced. The presence of Ag and Au nanoparticles in the OLEDs showed a blue and red shift of the emission wavelength, respectively. Also, the Ag and Au nanorods caused a significant reduction in the FWHM and a shift to the longer wavelengths in the structures. The structures containing Ag nanorods showed the narrowest FWHM and longer emission wavelength than the other structures.

贵金属，特别是Ag和Au纳米结构，在表面等离振子共振方面具有独特且可调节的光学属性。在这项研究中，使用有限差分时域（FDTD）方法研究了具有球形和棒状形状的Ag和Au纳米颗粒对OLED结构的光提取效率和FWHM的影响。仿真结果表明，通过改变Ag和Au纳米结构的形状和尺寸，可以调节发射波长，并且可以减小FWHM。OLED中Ag和Au纳米粒子的存在分别显示了发射波长的蓝移和红移。而且，Ag和Au纳米棒会导致FWHM的显着降低，并导致结构中的较长波长转移。
