Improvement of Power Efficiency in Phosphorescent White Organic Light-Emitting Diodes Using p-Doped Hole Transport Layer

Figure 6

(a)–(e) Normalized EL spectra of WOLEDs with different current density at fixed doping concentrations and (f) with different MoO3 doping concentrations at the same current density (  mA·cm−2). Each inset shows the corresponding CIE color coordinates. The arrows indicate the spectral and CIE color coordinates variations with increasing current density from 0.051 to 153 mA·cm−2.
