Abstract

In this work, we investigated the effect of increasing the thickness of Bphen layer on the luminous efficiency of organic light emitting diode. We could enhance the effectiveness of OLED by changing the doping concentration and thickness of the organic material. This research paper compare four OLEDs with varying thickness of electron transport layer keeping all other dimensions and material properties of the device same, The analysis is carried out on software SILVACO ATLAS 2D numerical device simulator and the optimum thickness of Bphen layer (4,7-di phenyl-1,10-phenantroline) layer is found as 15nm, and maximum luminous efficiency found as 3.90 cd/A at operating voltage of 5.2 volt.
