摘要

A class of hybrid materials based on indium 2,2'-bipyridine-5,5'-dicarboxylate metal-organic frameworks, In(OH) bpydc, was synthesized by postsynthetic introduction with lanthanide ions (Eu3+, Tb3+ and Sm3+). The structure, thermal stability, morphology and more detailed information about these materials were characterized by XRD, DSC, BET, FTIR, SEM and so forth. The further study of luminescent properties in detail showed that these compounds possess characteristic emission, and the In-MOF-Eu maintains different colors of light from blue-green to red under different excitation wavelengths (excited at 400 nm to 320 nm), which includes the near-white light region (the color coordinates are X = 0.34, Y = 0.36). It is a remarkable fact that the trend of ligand-central emission is opposite to that of the characteristic emission of Eu3+. Moreover, a kind of thin film and assembled white light near-UV LED based on the optically lanthanide-functionalized MOFs was prepared in order to extend their potential applications; both of them lead to desirable white light (X = 0.34, Y = 0.36; X = 0.35, Y = 0.37). In addition, the matrix does not affect the white luminescence.
