An efficient, stable OLED based on a single layer of a neat, thermally activated, delayed fluorescence emitter has been demonstrated by a research group at the Max Planck Institute for Polymer Research (MPI-P). The first prototype of the single-layer OLED is comparable in luminosity and efficiency to commercially available OLEDs.
The new OLED design consists of a layer that is supplied with electricity via two electrodes. The light-emitting layer is based on thermally activated delayed fluorescence (TADF). TADF-based OLEDs do not require expensive molecular complexes containing rare-earth metals like those being used in current OLEDs, the researchers said.
The first prototype of the OLED developed in Mainz, Germany, illuminates…READ MORE
