dc.description.abstract本論文主旨為研究在intra-cavity pumping架構下以紅色磷光有機發光二極體(OLED)光子源的電激發有機偏極子元件並透過該元件設計與實驗探討在不同共振角度及能態參數下其發光效率及機制。Intra-cavity pumping為直接激發偏極子能態發光,與non-resonant這種元件比較起來,更能降低偏極子散射時的損耗,並提高偏極子元件的的發光效率。Intra-cavity pumping的主要架構為在共振腔中置入高吸收層的有機材料作為激子庫,以及適合的寬頻光源的OLED作為激發光子源,並根據模層模擬使上述兩層中之電場最大化,因此針對這些進行模層結構高吸收層及光子源的優化。 實驗中使用紅色磷光發光二極體作為光子源,並根據實驗結果證明光子源的表現對於元件發光效率有很大的影響,實驗研究發現在室溫下intra-cavity pumping架構的電激發偏極子元件可以達到一定的發光效率約4%的EQE、6.8mW/cm2的光強與170meV的拉比分裂。此一結果,可進一步提供未來電激發偏極子雷射發展之基礎與重要參考。 zh_TW
dc.description.abstractIn this thesis, an electrically pumped organic polariton device embedded with a red phosphorescent organic light-emitting diode (OLED) as light source based on intra-cavity pumping structure is developed and its external quantum efficiency studied. Intra-cavity pumping is a kind of resonant pumping mechanism in a micro-cavity through an external voltage applied to excite the energy state of the polariton. Comparing with non-resonant pumping, the structure of the intra-cavity pumping performs better in reducing the energy loss in the process of polariton scattering and improve the luminous efficiency of polariton devices. The key feature of the intra-cavity pumping is to add a high absorption organic layer in the resonant cavity to trap polariton, and a suitable broadband light source layer, e.g. OLED, to generate photons as excitation light source. How to optimize the luminous efficiency in this composition of the polariton layer and organic photon source structure through various design parameters of this type of devices still remains a challenge In the thesis, we use red phosphorescent OLED as the photon source coupled with DEDOC as high absorption polariton source. From our experimental results, it is found that the performance of the photon source has impact on luminous efficiency on the device. The study shows that this kind of strong coupling device can achieve external quantum efficiency (EQE) about 4%, light intensity 6.8mW / cm^2 and rabi-splitting of 170 meV. The result can provide a foundation for future reference of improvement. en_US
