    Abstract: 本論文主要為研究intra-cavity pumping機制的電激發有機偏極子元件。intra-cavity pumping共振腔架構的設計概念為結合有機強耦合高吸收材料與弱耦合發光OLED,先產生弱耦合OLED的電激發光,再激發出共振腔偏極子能態的發光。其中高吸收材料與OLED以一介電層隔絕,使電流只通過OLED部份,因此不受高吸收材料電性所影響。相較於一般直接以電激發高吸收材料產生偏極子能態放光,intra-cavity pumping架構可同時針對弱耦合OLED的發光效率與有機強耦合材料的吸收特性分別進行優化,在有機材料的選擇上更具彈性與選擇性,偏極子能態的發光效率也更高。
    本論文電激發有機偏極子元件以DEDOC作為高吸收強耦合材料與DCJTB紅光OLED作為弱耦合發光源,在優化的元件製程條件之下可達到120 meV的拉比分裂及大於1 %的外部量子效率,為目前電激發有機偏極子元件最高的發光效率。此研究結果有助於未來發展高效率電激發強耦合元件和低閥值偏極子雷射。
    ;In this thesis, the electrically pumped organic polariton device by intra-cavity pumped was studied. The intra-cavity pumped microcavity consists of high absorption material and weak coupling OLED. In the intra-cavity pumped microcavity, a specific polariton mode is pumped by OLED emission and then emit light through the recombination process. In the microcavity, the high absorption layer and OLED are isolated by a dielectric layer such that the current only pass through the OLED.Thus Thus, the performance of the device would not be affected by the electrical property of the high absorption material. In comparison with the traditional structure, which directly pumps the high absorption material, the intra-cavity pumped device has multiple selectivities of organic material and high quantum efficiency because the emission efficiency of OLED and the high absorption material can be optimized respectively.
    In this thesis, the electrically pumped organic polariton device was fabricated with DEDOC high absorption material and DCJTB red OLED pumping source with Rabi splitting of 120 meV and more than 1% EQE, which is the highest emission efficacy of electrically pumped organic polariton device. This research will promote the development of high efficiency electrically pumped organic polariton devices as well as low threshold polariton laser.
