| Summary: | 碩士 === 國立中央大學 === 光電科學與工程學系 === 107 === 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.
