摘要：

In this research, the optimization of device structures of blue fluorescent organic light emitting diode (OLED) with WBH-301 doped with WBD-701 was fabricated. By adjusting the thickness of each layer in OLED structure as well as total thickness of device, the position of recombination zone was controlled and located in the central region of emitting layer (EML) that significantly increases device efficiency. The device showed the current efficiency of 8.7 cd/A at current density 50 mA/cm(2) and with Commission Internationale de L'Eclairage (CIE) coordinates (x = 0.17, y = 0.34). This efficiency enhancement is important for understanding and further improving high-performance fluorescent OLEDs.
