White Organic Light emitting diodes based On exciplex states by using a new carbazole derivative as single emitter Layer

In this work we report the fabrication of organic light-emitting diodes based on the carbazole derivative 1,4-bis(9H-carbazol-9-yl)phenyl)ethynyl)benzene, showing excellent CIE coordinates (0.31, 0.33). To achieve this, we developed an initial architecture where the emissive layer was sandwiched between ITO/PEDOT:PSS, that acted as anode/hole transport layer, and Ca/Ag as cathode. The electroluminescence for this initial architecture was similar...
