Abstract

In this study, we have applied a new iridium(Ir) complex as a red dopant and fabricated a red phosphorescent organic light emitting diodes(OLEDs) on a flexible polycarbonate(PC) substrate. Also, we have investigated the electrical and optical properties of the devices with a structure of Al/LiF/Alq 3/(RD05 doped)BAlq/NPB/2-TNATA/ITO/PC substrate. Our device showed the lightening efficiency of > 30 cd/A at an initial brightness of 1000 cd/m 2. The CIE(Commission Internationale de L'Eclairage) coordinates for the device were (0.62, 0.37) at a current density of 1 mA/cm 2. In addition, although the sheet resistance of ITO films on PC substrate is higher than that on glass substrate, the flexible OLED showed much better lightening efficiency without much increase in operating voltage. copyright The Electrochemical Society.
