Kaskel, S.S.KaskelSchrage, C.C.Schrage2022-03-082022-03-082008https://publica.fraunhofer.de/handle/publica/308745A lighting element includes a luminescent layer (3), which is arranged between two flat electrodes (1,2). The luminescent layer is suitable for alternating field electroluminescence excitation. The electrodes are formed as an optically transparent layer with carbon nanotubes or graphene, where the carbon nanotube is a single-walled carbon nanotube. The electrode or a dielectric intermediate layer is arranged on a substrate (4,5). An independent claim is included for a method for producing lighting element, which involves forming optically transparent electrode on luminescent layer through dispersion using liquid, carbon nanotubes or grapheme, where the formed electrode is washed with ethanol and then dried.de621patent102008039756
