Metal-organic frameworks (MOFs) are a class of crystalline porous coordination materials, which assembled from inorganic nodes and organic linkers. Numerous applications, such as gas storage, molecule separation, catalysis, optical sensing, charge transport, benefit the outstanding properties MOF materials. More advanced e.g., in electronics optoelectronics area, demand homogeneous monolithic thin films. Recent studies demonstrated that surface-mounted MOFs (SURMOFs) well suited to fulfill...

Abstract By using a layer‐by‐layer (LbL) approach, lanthanide‐based, monolithic metal–organic framework (MOF) thin films are fabricated for optical applications. In particular, the LbL approach allows manufacturing of heteroepitaxial Tb(III)‐Eu(III)(BTC) coatings with precise thickness control. Adjusting Tb(III)‐to‐Eu(III) ratio tuning emission color. The hetero‐multilayer architecture makes it possible to suppress direct energy transfer, an unwanted phenomenon present in corresponding...
