- W4288792237 abstract "In this project, we start with optical simulation of an OLED to have a basic understanding of the mode dispersion inside the device. We first fabricated 1-D photonic crystals’ (PhCs) for corrugated green OLED devices observed enhanced EQE from 20% to 27%, which has the drawbacks of angular color shift. To resolve this issue, we fabricated poly crystalline PhCs (poly PhC) devices and observed alleviated angular color shift. The outcoupling efficiency is enhanced from 30% to 35%, which can be further enhanced to 60% by extracting the substrate mode. To further enhance the efficiency, we used RCWA (rigorous coupled-wave analysis) simulation to study the optical property in the corrugated device. We found out the corrugation reduces the reflectance of the Al cathode, lowers the cavity resonance and weakens the cavity emission. To preserve the cavity effect, we insert a low index Teflon layer (n = 1.3) between the ITO anode and the corrugated substrate, which increased the index contrast and hence the reflectance of the bottom electrode. As a result, the corrugated OLED with a Teflon layer shows a maximum outcoupling efficiency of 75%." @default.
