In order to realize organic electro-optical devices with high speed operation, electro-optical devices have been fabricated by solution process with simple fabrication technique. The fabricated devices have been operated with similar characteristics with those fabricated by vacuum process. Both the light emitting anddetection devices can be operated above 80 MHz. Insertion of self-assembled monolayerbetween electrode and organic layer improves carrier injection and control the carrier trap formation, and results in high speed operation. The devices parameters are analyzed by impedance spectroscopy.

为了实现高速运行的有机电光器件，已经通过溶液法以简单的制造技术来制造电光器件。所制造的器件具有与真空工艺制造的器件相似的特性。发光和检测装置均可在 80 MHz 以上运行。在电极和有机层之间插入自组装单层可以改善载流子注入并控制载流子陷阱的形成，从而实现高速运行。通过阻抗谱分析器件参数。
