Abstract
In this work, the effect of replacing traditional indium tin oxide (ITO) anode with different anode materials is reported. The detailed simulation is conducted on organic light-emitting diode (OLED) consisting of commonly used emissive or organic layers with tris(8-hydroxyquinoline) aluminum (Alq3) at an operating wavelength of 540 nm. Different device simulations using aluminum zinc oxide (AZO), zinc mono-oxide (ZnO), graphene (7 nm/12 nm), and silver (Ag) anode materials with different work functions are modelled and simulated. For measuring OLED's optical results, the finite difference time domain (FDTD) approach was used. The angular distribution of OLEDs with reference to viewing angle with different anodes is reported. The results show the optical effects of the anode material with Graphene has better enhancement in light output compared to other materials. This work shows the far field contours of all the anode materials that improve light production and that optimum emission from an OLED to check the alternative to indium tin oxide anode material.
