摘要：

Metal-organic frameworks (MOFs) have received notable attention owing to their structural diversity, permanent porosity, and high surface areas. In addition to these properties, rare-earth (RE) MOFs have the added feature of tunable photoluminescence dictated by the identity of the metal ion and organic linker in the RE-MOF. Herein, we explore the tunable photoluminescent properties of RE-UiO-66 by synthesizing and characterizing mono-, bi- and tri-metal RE-UiO-66 analogues where RE = Tb(III), Gd(III), and Eu(III), to ultimately design a white light emitting MOF. The photophysical properties of this series of MOFs are explored and, as a proof of concept, the tri-metal Tb:Gd:Eu-UiO-66 is used as a surface coating on a UV light emitting diode (LED) to give a white light emitting device.
