Abstract:	本論文主旨為研究在intra-cavity pumping架構下以螢光OLED作為光子源之電激發有機偏極子。Intra-cavity pumping機制元件為直接激發偏極子能態發光，與一般偏極子元件相比，能降低偏極子散射的損耗，提升元件發光效率。其元件主要架構為在共振腔中置入高吸收的有機材料產生偏極子能態，以及合適的OLED作為光子源激發偏極子能態放光。實驗研究中，偏極子元件以DCM橘紅光OLED與DCJTB紅光OLED作為光子源。藉由比對元件電性與光性表現，顯示光子源的發光效率對偏極子能態發光效率有直接的影響，而改變高吸收材料厚度，可調變偏極子元件拉比分裂大小，且不會影響偏極子能態發光效率。因此在未來進行偏極子元件研究時，能分別對光子源和吸收層進行優化達到最佳發光效率。 ;In the thesis, the electrically pumped organic polariton device with fluorescent OLED under the intra-cavity pumping structure was studied. The intra-cavity pumping polariton device can directly pump the polariton state to emit light, which can reduce the loss of the scattering of the polariton and improve the EQE of the polariton device. The main structure of the polariton device is to deposited a highly absorbing organic material in the resonant cavity to generate a polariton energy state, and a suitable OLED as a pumping OLED to excite the polariton state. In this research, the pumping OLED of the polariton device is DCM orange OLED and DCJTB red OLED. By comparing the electrical and optical properties of the devices, it is shown that the EQE of the pumping OLED has a direct influence on the EQE of the polariton state. The thickness of the high-absorbing material is modulated, and the Rabi splitting energy of the polariton device can be adjusted without affecting the EQE of the polariton state. In the future research of polariton device, the pumping OLED and the absorption layer can be optimized respectively to achieve the best EQE.
