In this research article, the emphasis is given on the simulation of optical and electronic characteristics of ITO/NPB/Alq₃:DCJTB/Alq₃/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 Alq₃ 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 ∼ 4 V and the highest luminous flux of the designed OLED corresponds 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 ∼ 4 V.

在这篇研究文章中，重点放在基于ITO / NPB / Alq ₃：DCJTB / Alq ₃ / Ag异质结构的有机发光二极管（OLED）的光学和电子特性的仿真上。在模拟下，研究了与EML和ETL相关的激子的行为，其阳极电压和电流发生了变化。为了模拟光谱特性，Holstein模型已用于Alq ₃和电子传输层和发射层中的DCJTB光谱。光子传播模型已用于研究珀塞尔因子。结果，我们获得了I–V特性，发光功率，输出光谱功率密度，光谱辐射度和光谱光通量。根据获得的结果，发现工作电压约为4 V，设计的OLED的最大光通量在可见光区域对应于565 nm（黄色/橙色）。因此，设计的OLED可能非常适合在非常低的电压〜4 V下发射黄/橙色光。
