Self-assembled 3D flower-like TiO2:Eu3+ microspheres have been synthesized by a simple hydrothermal method and crystallized by subsequent heat treatments at elevated temperatures. The as-prepared samples are loose and porous with flower-like structure, and the subunits are irregularly shaped nanosheets. A possible growth mechanism is proposed for the 3D flower-like TiO2:Eu3+ microspheres, and it was...
Highly monodispersed SiO 2 @Lu 2 O 3 :Eu 3+ core–shell microspheres were successfully synthesized by coating the Lu 2 O 3 :Eu 3+ nanoparticles onto the surface of non-aggregated spherical SiO 2 particles via a simple solvothermal method, followed by a subsequent calcination process. The as-prepared phosphors were characterized by X-ray...
