Abstract: (432 Views)
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 nanorods 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 size of Ag nanostructures, the emission wavelength can be adjusted, and the FWHM can be reduced. The presence of Ag nanorods caused a significant reduction in the FWHM and a shift to the longer wavelengths in the structures. The simulation results showed that using Ag nanorods in the middle of the electron transfer layer (Alq3), the FWHM decreased from 150nm to 29 nm and the emission peak shifted from 530 nm to 844 nm.
