摘要：
We studied the exciplex kinetics in nanocrystal organic light-emitting diodes (NC-OLEDs) where the emissive layer of inorganic nanocrystal quantum dots is sandwiched between the electron and hole transport layers of organic semiconductors at the organic–organic interface. We modeled exciplex generation, diffusion, recombination, and capture by nanocrystals via the Förster mechanism in NC-OLEDs. The exciplex kinetics determines the NC-OLED operation characterized by the quantum yield efficiency and emission intensity and it can be optimized by controlling the nanocrystal separation in the NC-OLED.
