Photophysical Characterisation of Thermally Activated Delayed Fluorescence (TADF) Materials
Piotr Pander and Fernando B. Dias
In this work we present a brief characterization of thermally activated delayed fluorescence (TADF) emitters and describe the spectroscopic methods used to investigate them. Both steady state and time-resolved methods are presented. The effect of oxygen on delayed fluorescence is described. Three different TADF emitters are compared to evaluate the effect of different electron-donating groups on their spectroscopic properties.
