[摘要]：We describe self-organization-reorganization of a lanthanide (Ln)-surfactant lamellar hybrid with intense photoluminescence and controlled nanostructures. We reveal that UV luminescence exhibited by a Ce-dodecyl sulfate (DS) lamellar hybrid offers the maximum quantum yield (QY) of 90% among all types of Ce-organic hybrid materials. In addition, Ce-Tb dodecyl phosphate (DP) lamellar hybrids exhibit bright green emission due to the two-dimensional Ce3+-Tb3+ energy transfer (ET) process in Ln-PO4 layers. Furthermore, a Ce-DS film with a highly oriented nanostructure and Ce-Tb-DP colloidal nanosheets are fabricated through simple and effective reorganization routes. The concept of "reorganization routes" opens up new pathways to general-and large-scale fabrication of two-dimensional nanomaterials on the basis of metal-surfactant assemblies with a variety of physical and chemical properties. |
