Abstract
A novel yttrium complex [Y(HIA)3(H2O)2]n·nYCl3 (HIA = isonicotinic acid) has been synthesized via a hydrothermal reaction and characterized by single crystal X-ray diffraction technique. The title complex features a one-dimensional (1-D) chain-like structure. A solid state photoluminescence measurement revealed that there is one strong emission peak at 487 nm. These peak can be assigned to the characteristic electronic transition and stacking effect inside the ligand. The title complex shows CIE (Commission Internationale de I’ Éclairage) chromaticity coordinates in the blue region (0.1049, 0.1221). At the same time, the title complex has a wide band gap of 2.03 eV, which was revealed by a solid-state UV/Vis diffuse reflection experiment.
