OLED的高响应速率的特点可以作为电/光转换器件应用到通信领域，尤其是红色有机电致发光器件（R-OLED）与聚合物光纤（POF）低损耗窗口相匹配，可以与有机光探测器（OPD）共同集成到POF上。为了提高传输功率和传输距离，要求通信光源具有高输出功率，面向短距离局域网络有机光纤通信系统设计一组基于染料Ir（piq）2acac不同结构的R-OLED，其中混合母体中间层结构相比于单发光层器件，最大电流效率提高了66%。提出的结构可以有效提高器件效率，结合新材料可以得到更高输出功率信号源。

Organic Light Emitting Device (OLED) is able to act as an electrical/optical conversion device for application in the field of optical communication due to its high response speed. In particular, red OLEDs (R-OLEDs) of the suitable wavelength can be integrated with organic light detector (OPD) on polymer optical fiber (POF) to assemble organic fiber-optic communication LAN system because OLEDs can be deposited on various substrates under room ambient. As an electrical/optical conversion device, high emission efficiency would be of great importance. In this paper, we fabricated a set of R-OLEDs based on Ir (piq)2acac with different device structures. The device efficiency is increased to 5.2 cd/A by utilizing intermixed host structure, which improves 66%as compared to the reference device. Device with the structure of new material would achieve a quite high efficiency as optical source.
