- Abstract
- White organic light-emitting diodes were fabricated with two separated emissive layers using a blue fluorescent dopant and a red phosphorescent dopant. The L-V characteristics of the device A and B showed maximum luminance of 26100 and 21100 cd/m2 at 14 V and the maximum luminous efficiency of the devices showed 11.3 and 9.7 cd/A, respectively. The CIEx,y coordinates of device A and B showed (x = 0.27, y = 0.35) and (x = 0.33, y = 0.33) at 10 V. White device used BAlq as a host demonstrated proper white CIEx,y coordinates and also showed white emission at operating voltages (4 V -14 V) without shifting of CIEx,y coordinates.
