Abstract:

Terbium-based coordination polymer (Tb-CP) microspheres with diameters ranging from 0.8 to 1.5 μm were prepared from Tb(NO₃)₃ and 2-nitroterephthalic acid at 160 °C for 6 h. Their composite film with polymethyl methacrylate was prepared by spin-coating method. The products were fully characterized by SEM, TEM, PXRD, TG, FT-IR, and PL. Eu³⁺-doped Tb-CP microsphere and its film were prepared and their luminescent properties were investigated. It turns out that the hetero-metal CPs only exhibits the characteristic emission peak of Eu³⁺, indicating metal-to-metal charge transfer from the Tb³⁺ to Eu³⁺ centers.
