Popis:	The approach towards the increase of the terbium electroluminescence efficiency by the increase of the transport properties was further developed. Therefore, terbium-based emitters, containing anionic ligands, able to both increase the hole mobility and to sensitize terbium luminescence, were purposefully obtained within the composite films, containing the recently studied host material PO4, able to increase electron-transport properties and also to ensure terbium luminescence. As a result, the luminance of 332 cd/m2 was reached, which is one of the highest results for solution-processed OLEDs based on terbium complexes.
