Publication in Adv. Mater., Optimizing the Emission Zone using a Single-Emission Spectrum Technique
In Advanced Materials, we recently demonstrated record TADF OLED lifetime (measured 4500 hours to 95% brightness at 1000 cd m-2), which also featured 20% EQE. This was achieved by optically measuring where the light is emitted from (the emission zone) to several nm accuracy.
With this new method, one must only measure only the 0 degree emission spectrum (which is measured in all OLED labs already) and the layer n,k data.
Thanks to the great collaboration of colleagues at imec Belgium and i3-opera Japan.
