A family of luminescent microporous lanthanide silicates

摘要：

Mild hydrothermal synthesis has been utilized to prepare a series of luminescent microporous lanthanide silicates, denoted as LnSiO-CJn (n = 1-6, Ln = Ce, Tb, or Eu). Their structures have been determined by single-crystal X-ray diffraction analysis. These lanthanide silicate structures are built up from SiO4 tetrahedra and Ln-centered polyhedra (LnO6, LnO7 or LnO8) to form three-dimensional (3D) open frameworks. Their structures contain 8-ring or 9-ring channels in which alkali ions (Na+ or K+) and water molecules reside. The LnSiO-CJn compounds show interesting photoluminescent properties.
