We report highly efficient near‐infrared (NIR) phosphorescent OLEDs. In particular, we report PHOLED performance with emission peak wavelength at ~800 nm (FWHM=65 nm and PLQY=0.36) with a maximum EQE (EQEmax) of 9.7%, and an EQE of 8.8% at 10 mA/cm2 (EQE10mA/cm2). Its narrow electroluminescence spectrum results in cal. >83% of emission is above 780 nm and >97% of emission is above 750 nm. This device shows the best performance among reported NIR OLEDs.
