| dc.description.abstract | 本論文主要研究在共振激發機制下的電致發光偏極子元件，我們以高分子材料MDMO-PPV同時作為激子庫與光子源，透過共振腔式倒置型高分子發光二極體的設計，實現高分子材料的激子能量與共振腔光子模態的強耦合作用，並使電激發的光源直接激發偏極子能態發光，與一般元件相比，可以減少偏極子散射的損耗，提升元件發光效率。
在加入電子傳輸層ZnO優化元件後，實驗得到元件的外部量子效率約為0.14 %，偏極子集中於下支低角度發光，拉比分裂能量為600 meV，耦合因子有22.9 %，屬於超強耦合的範疇。而在強弱耦合元件發光效率的比較下，推測ZnO鍍在不同膜面上的電子注入效果不同，並以單載子元件的實驗證明。

| dc.description.abstract | In this thesis, the electrically pumped polariton device operating in the resonant pumping regime was studied. We used polymer material MDMO-PPV as both exciton reservoir and photon source. Via design of microcavity inverted polymer light-emitting diode, strong coupling between exciton energy of polymer material and photon mode of microcavity was achieved. And the electrically excited light source can directly pump the polariton energy state to emit light. In contrast to general device, it can reduce the loss of polariton scattering and improve the luminescence efficiency.
After adding electron transport layer ZnO for optimizing the device, the experiment have shown that external quantum efficiency is 0.14% and light-emitting polaritons gather in the lower branch at low angle. Rabi splitting energy is 600 meV which corresponds to a coupling factor = 22.9 %. It reach the ultrastrong coupling regime. Comparing the luminescence efficiency of strong coupling device with weak coupling device, we guess that the electron injection capability of ZnO deposited on the different film are different and prove by experimental result of electron-only device.
