英语翻译To improve light extraction from organic light-emitting

英语翻译
To improve light extraction from organic light-emitting diodes(OLEDs),we introduced a photonic crystal pattern into the glass substrate of an OLED.The periodic modulation converts the guided waves in the high-refractive-index indium-tin-oxide/organic layers into external leaky waves.We used the finite-difference time-domain method to optimize the structural parameters of the photonic crystal pattern and to analyze the microcavity effect by the metallic cathode of the OLED.With the use of an optimized photonic crystal pattern,an increase of over 80% in the extraction efficiency of the OLED is expected theoretically.An increase in the extraction efficiency of over 50% was achieved experimentally,without detriment to the crucial electrical properties of the OLED.
There have been various efforts to increase the extraction efficiency of organic light-emitting diodes (OLEDs).The extraction efficiency is related to the intrinsic photoluminescence efficiency of the organic material and to the output coupling efficiency of the sandwiched indium-tin-oxide(ITO)/organic layers.The intrinsic efficiency has been considerably improved by the use of phosphorescent harvesters1.However,the output coupling efficiency in these systems remains very small(
