Monodisperse rutile microspheres with ultrasmall nanorods on surfaces: Synthesis, characterization, luminescence, and photocatalysis

Three-Dimensional Titanium Dioxide Nanomaterials

“…Rutile titania morphologies are also formed in a hydrothermal reaction of titanium n -butoxide in concentrated hydrochloric acid, or in a mixture of oleic and hydrochloric acids , at 180 °C. HCl plays a key role in guiding the structures and morphologies of the formed titania particles, which can be cuboid, flower, cauliflower, and ball-shaped depending on the volume of concentrated acid.…”

Fabrication and photoluminescence properties of TiO2:Eu3+ microspheres with tunable structure from solid to core–shell

“…9 Due to its chemical stability, easy synthesis, low cost, non-toxicity, and non-hygroscopic performance, titania (TiO 2 ) is suggested to be a promising host material for the luminescence of various rare earth ions. [10][11][12] Therefore, many efforts have been devoted to explore various morphologies of TiO 2 -based phosphors, such as nanorods, 13 nanotubes, 14 nanowires, 15 nanorings, 16 nanoplates, 17 microspheres, 18,19 core-shell structures, 20 hollow spheres, 21 etc. However, to the best of our knowledge, there have been few reports on the synthesis and the corresponding luminescence of uniform, well-dispersed submicron-scale Eu-doped TiO 2 spheres with tunable structure from solid to core-shell.…”
