Photoluminescent Layered Lanthanide Silicate Nanoparticles
Ananias, Duarte; Ferdov, Stanislav; Paz, Filipe A. Almeida; Ferreira, Rute A. Sá; Ferreira, Artur; Geraldes, Carlos F. G. C.; Carlos, Luís D.; Lin, ZhiThe first examples of nanoparticles of pure layered Ln2(SiO4H)(OH)2(H2O)Cl (where Ln ) Eu, Gd, and Tb) and mixed microcrystalline layered lanthanide silicates containing different Eu/Gd and Tb/Gd ratios have been reported. The crystal structure of these silicates has been solved from synchrotron powder X-ray diffraction data. These materials display interesting and tuneable photoluminescence (PL) properties, su...
