Interfacing Lanthanide Metal‐Organic Frameworks with ZnO Nanowires for Alternating Current Electroluminescence (Small 4/2024)

Metal‐Organic Frameworks In article number 2305251, Yu Tang, Feng Wang, and co‐workers devise a Ln‐based alternating current electroluminescence (ACEL) device which includes a novel lanthanide‐benzenetricarboxylate (Ln‐BTC) emitting layer and a PMMA insulating layer sandwiched between two ITO electrodes (bottom to up). The Ln‐BTC thin film is constructed by growing Tb/Eu‐BTC multipod arrays on brass grid substrate seeded with ZnO nanowires (NWs) as anchors. By controlling lanthanide composition in the metal‐organic framework (MOF) film, electroluminescence (EL) color can be continuously tuned from red to green.
