Abstract

In this paper, we report an accurate optical calculation method of tandem organic light-emitting diode (OLED) with consideration of Purcell effect. Using the normal reported method, there are some discrepancies between calculation and experimental external quantum efficiencies. To improve such discrepancies, we considered Purcell effect in optical calculation method. This improved calculation with Purcell effect were well matched with experimental results. Additionally, we measured exciton lifetime to identify the validity of Purcell factor which was applied to calculation. Through this measurement, we identified theoretical calculation is well matched with experimental tendency. Thus, this calculation can be more useful in tandem OLED applications.
