The paper introduces MR-TADF emitters into light-emitting electrochemical cells (LECs) for narrowband and efficient emission. It demonstrates a metal-free MR-TADF LEC delivering blue light with a narrow full-width-at-half-maximum (FWHM) of 31 nm, a high external quantum efficiency of 3.8%, and significant electrochemical doping capacity.

How Setfos was used

Setfos was used to perform optical simulations, helping to understand and optimize the emission and efficiency of the device by simulating the position of emissive dipoles within the active material.
