Abstract
This article reports the optimized structure of (NPD/PC60BM/BPhen/TPBi) organic light-emitting diode (OLED) heterostructure having overall size (width) ~ 500 nm and its various characteristics. In the optimized OLED structure, two electron transport layers (ETLs) of the TPBi and BPhen organic polymers have been used for getting higher performance. For the designed OLED structure, energy band diagram, current-voltage (I-V) and current density-voltage ( J-V) characteristics, behavior of voltage and current dependent light flux, optical efficiency along with the recombination prefactor have been studied. The turn on voltage is found as ~ 3.5 V, while the optimum value of optical efficiency is obtained at ~ 3 V. The probability with which photons are escaped from the device is found out maximum for 600 – 700 nm wavelength range.
