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

<table>Optical absorption spectra of MoO<sub>3</sub>, undoped TAPC, and MoO<sub>3</sub>-doped TAPC films with different MoO<sub>3</sub> concentrations. Inset: increase of CT complex absorption peak (703 nm) as the MoO<sub>3</sub> concentration increases.</table>
