摘要:
采用偶极子源项和转移矩阵来描述结构内外的光电场分布,并通过Matlab编程,建立了符合有机发光二极管(OLED)实际器件的光学模型。利用该光学模型进行模拟计算具有NPB/Alq3结构的OLED,得到了电致发光(EL)光谱与器件中光出射角之间的关系并结合人眼视觉函数,得到器件亮度与角度的关系,当出射角度逐渐增大时,亮度逐渐减小。另外,制备了不同8-羟基喹啉铝(Alq3)电子传输层厚度的器件,并测量其电致发光光谱,发现模拟计算的理论光谱与测量结果相吻合。并且还发现随着Alq3有机层厚度增加,OLED电致发光光谱的峰位会发生一定的红移。
Abstract:
Based on dipole emission source term and transfer matrices,an optical model to describe the optical electric field distribution inside the device structure of organic light emitting diodes(OLED)was developed by Matlab.By using the optical model,the electroluminescence(EL)spectra of OLED with a structure of NPB/Alq3 were simulated,and the relationship between EL spectra and the emission angle was built.The relationship between device luminance and emission angel could also be established with the help of photonic response function.When the emission angle increased,the brightness of the device decreased.In addition,the OLED with different thicknesses of Alq3 were fabricated and the EL spectra from these OLED were measured.It was found that theoretical EL spectra were in good agreement with the experimental results,and the EL spectrum was red-shifted when the Alq3 thickness increased.
