P‐15.31: Extremely High‐efficiency OLEDs by Phosphorescent Sensitized Devices

In this paper, a method for further improving the efficiency of top emission organic light‐emitting diodes (TE‐OLEDs) by phosphorescent sensitized fluorescent organic light‐emitting diodes (PSF‐OLEDs) was provided. The maximum current efficiency (CE) of PSF‐OLEDs realized an improvement of nearly 40% compared with the phosphorescent device, which exhibited great potential in high‐efficiency OLEDs.
