ORGANIC LIGHT EMITTING FIELD EFFECT TRANSISTOR

摘要

The present invention relates to an organic light emitting field effect transistor, OLEFET, (10) comprising a gate (G), a source (S) and a drain (D) electrode; a layered organic stack structure (1) including an organic layer (4) with predominant hole transporting character, an organic layer (2) with predominant electron transporting character and an organic active layer (3) having light emitting properties,the organic active layer (3) being interposed between the predominant hole and electron doped transport layers (4,2). The organic layer (4) with predominant hole transporting character and/or the organic layer (2) with predominant electron transporting character is doped in order to enhance the transport of holes/electrons. In addition, the layered organic stack structure (1) is positioned between said gate (G) and said source-drain electrodes.
