Two Ln-based Metal-Organic Frameworks (MOFs), Eu-BCTC and Tb-BCTC, were synthesized using the ligand [9,9 '-bicarbazole]-3,3 ',6,6 '-tetracarboxylic acid (H4BCTC) via a solvothermal method. They emit green or red light, respectively. By adjusting the molar ratio of Eu3+/Tb3+ of LMOFs, a single-phase white light emitter, Eu0.075Tb0.925-BCTC, was successfully synthesized. This compound exhibits an ideal CIE coordinate of (0.33, 0.33), internal quantum yield (IQY) at 8.37 % and a color temperature of 5623 K. Moreover, it has excellent performance in detecting Fe3+, Cr2O72- and CrO42- , with limit...
