| Abstract: | An elementary approach has been suggested to calculate the external quantum efficiency (EQE) of polymer light emitting diodes (PLEDs). This approach requires only the electroluminescence (EL) spectrum and illumination versus current characteristics of the devices to calculate the EQE. In these calculations the light emission has been considered to be perfectly diffusive from the emission surface. The efficiencies calculated in this way have been compared with the actual values of the EQEs for the different PLED structures available in the literature. The calculated values have shown good agreement with the measured values. |
