Photonic Crystals from Monodisperse Lanthanide‐Hydroxide‐at‐Silica Core/Shell Colloidal Spheres

Optical and structural properties of nanostructured CeO2:Tb3+ film

“…In addition, the broadening in the XRD reflection planes owing to the increased lattice defect and disorder formation induced by doping [2,4]. Lin et al reported increase lattice constant value due to the lattice expansion effect resulting from increase oxygen vacancies and Ce 3+ ions with decreasing particle size [28].…”

Catalytic photodegradation of Congo red in aqueous solution by Ln(OH)3 (Ln = Nd, Sm, Eu, Gd, Tb, and Dy) nanorods

“…The 1D rare-earth nanomaterials can be used as fluorescent materials, which can significantly improve the screen coating uniformity, that is particularly useful for the advancing the clarity and the resolution in plasma display panels (PDP) [12,13]. For instance, Eu(OH) 3 is a type of very good luminescent material, which is typically used for the preparation of Eu 2 O 3 [14]. Gd(OH) 3 can also be used for catalysis, adsorbent and as Gd 2 O 3 precursor.…”

Preparation of silica microspheres coated with V2O5 xerogel and V2O5/WO3 composite xerogel via adapted Stöber process

“…Monodispersed colloidal particles with uniform size, shape and composition have a myriad of potential applications in catalysis, ceramics, chromatography, membranes, pigments, among other areas [1][2][3]. Therefore, several research groups have devoted their attention to the fabrication of spherical particles of hydrated oxides via both alkoxide hydrolysis and inorganic salt solutions such as those of ZrOCl 2 and FeC1 3 [4,5].…”

“…An and co-workers have developed a method for the fabrication of a silica nanoparticle film based on the covalent-bonding interaction between carboxylic acid-functionalized silica nanoparticles (SiO 2 -COOH) [15]. Lin et al have synthesized monodispersed lanthanide-hydroxide-at-silica nanoparticles, whose colloidal particle size can be precisely controlled and self assembled into a photonic crystal [3].…”
