Challenge	OLEDs, despite their advantages, suffer from significant light loss and energy inefficiency. Researchers at Konica Minolta are working to address these issues by understanding and mitigating the complex plasmon coupling phenomenon, which accounts for 40% of the light lost in OLEDs. This phenomenon involves the interaction of light with surface plasmons at the interface between the cathode and the organic material, leading to energy dissipation as heat. The challenge is to find ways to reduce these losses and improve the overall efficiency and brightness of OLEDs. Read More

Solution	The team at Konica Minolta Laboratory USA, led by senior researcher Leiming Wang, utilized numerical simulation in COMSOL Multiphysics® software to analyze and address light-loss mechanisms in OLEDs. They focused on the coupling of dipole emission with surface plasmons at the cathode-organic material interface, which leads to significant energy loss. By modeling light emission and surface plasmon polaritons (SPPs), they explored various cathode structures, including a nanograting design, to disrupt the formation of SPPs and reduce energy coupling. The simulations revealed that the optimized nanostructure surface for the cathode could reduce plasmon losses by 50%, significantly improving the efficiency and brightness of OLEDs. The versatility and user-friendliness of COMSOL Multiphysics® allowed the team to perform comprehensive simulations, including postprocessing data and incorporating wavelength-dependent optical properties, to achieve these results.
