Rates and singlet/triplet ratios from TADF transients
Mitchell C. Nelson
Thermally activated delayed fluorescence has been reported in a number of OLED emitter materials engineered to have low singlet-triplet energy gaps. Here we derive closed solutions…
Efficiency and Stimulated Emission in Quarter Wave OLEDS
Mitchell C. Nelson
Quarter-wave OLEDS are microcavity devices that can operate in the low finesse limit and achieve high efficiency (> 300 lm/W) by using interference to reduce the onset current for…
Asymptotic Efficiency in OLEDS
Mitchell C. Nelson
Asymptotic efficiency (high output without droop) was recently reported for OLEDS in which a thin emitter layer is located at the anti-node in a resonant microcavity. Here we exten…
High output efficiency (340 lm/W) in a one wavelength microcavity OLED with emitter layer positioned at an anti-node
Mitchell C. Nelson
An OLED architecture is described in which a thin emitter layer is located at the anti-node of a resonant microcavity. In two realizations, the mode space is constrained by either…
