本論文主要研究PFO:F8BT based OLED作為光子源應用於電激發偏極子元件。首先我們優化OLED的電子注入端進而提升外部量子效率(EQE)近2%作為光子源與提供激子的高吸收染料分子DEDOC強耦合產生偏極子，接著以intra-cavity pumping的共振腔架構設計偏極子元件，其機制為激發強耦合能態，而光子源與吸收層之間以絕緣層隔絕限制電流只通過OLED，在此架構下可替換不同波長之光子源並適當調整腔長優化偏極子元件的效率。 實驗結果證明，當F8BT的放光接近激子能態，於EL光譜中同時觀察到不同偏極子的放光。此研究有助於理解強耦合的物理並發展低閥值雷射。 ;In this thesis, the PFO:F8BT based OLED was applied to electrically pumped organic polariton device as optical pumping source.We optimized the electron injection to increace external quantum efficiency(EQE) of OLED by nearly 2% as a pumping source and strongly couple the highly absorption dye.The polariton device is designed with the intra-cavity pumping. The mechanism is to excite the strong coupling energy state.We Use insulation separate OLED and active layer,leading to the current only flow past OLED.Under this architecture,it is possible to replace pumping sources of different wavelengths and adjust the cavity length to optimize the current density and EQE of the polariton device. The result shows that when the emission of F8BT is nearly to the exciton reservior,the emission of exciting the upper branch and the lower branch can be observed .This research result will promote to understand physical mechanism of polariton and advance low threshold polariton laser.
