In this paper, an anionic metal-organic framework Bio-MOF-1 (Zn8(ad)4(BPDC)6O·2Me2NH2) and a luminescent complex (Sm3+ doped TiO2, labeled as Sm3+@TiO2) have both been prepared as previous reports and their photophysical properties are investigated. Subsequently, Tb3+ is introduced to Bio-MOF-1 via cation exchange and the obtained Tb3+@Bio-MOF-1 can exhibit(More)
Luminescent rare earth coordination polymers [H2NMe2]3[Y(DPA)3] ([H2NMe2]+ = dimethyl amino cation; H2DPA = 2,6-dipicolinic acid) are synthesized and is further modified by the ionic exchange reaction of [H2NMe2]+ cation with rare earth ions, which is named as RE3+ ⊂ [Y(DPA)3] (RE = Eu, Tb, Sm, Dy) hybrid systems. The multi-color can be tuned for these(More)
Highly luminescent hybrids N-GQDs/Eu(3+)@Mg-MOF (N-GQDs = N atom doped graphene quantum dots and Mg-MOF = {[Mg3(ndc)2.5(HCO2)2(H2O)][NH2Me2]·2H2O·DMF}) have been synthesized and their photophysical properties were investigated. The resulting luminescent material can exhibit dual-emission from N-GQDs and Eu(3+) when excited at 394 nm, whereas the emission of(More)
