Abstract
In this research article, the emphasis is given on the simulation of optical and electronic characteristics of ITO/NPB/Alq(3):DCJTB/Alq(3)/Ag heterostructure based organic light emitting diode (OLED). Under simulation, the behavior of excitons associated with EML and ETL have been studied with variation in anode voltage and current. In order to simulate the spectral characteristics, the Holstein model has been used for the Alq(3) and DCJTB spectra in electron transport and emissive layers. The photon propagation model has been used to study the Purcell factor. In results, we have achieved I-V characteristics, luminescent power, output spectral power density, spectral radiance and spectral luminous flux. According to the results achieved, the operating voltage is found similar to 4 V and the highest luminous flux of the designed OLED corresponds to similar to 565 nm (yellow/orange color) in visible region. Hence, the designed OLED may be very suitable for emission of yellow/orange light at very low voltage similar to 4 V.
