Bifunctional highly fluorescent hollow porous microspheres made of BaMoO4 : Pr3+ nanocrystals via a template-free synthesis

Bifunctional highly fluorescent hollow porous microspheres made of BaMoO 4 : Pr 3 + nanocrystals via a template - free synthesis †

nanocrystals by a facile template-free synthesis. All the as-synthesized hollow microspheres are welldispersed with a diameter of 2–4 mm and the BaMoO4 : Pr 3+ nanocrystals measure 30–60 nm in diameter. It is observed that there are a large amount of pores with an average diameter is 17.5 nm in the shell of these BaMoO4 : Pr 3+ hollow microspheres, thereby exhibiting a great promise for drug de...

Facile synthesis of folate-conjugated magnetic/fluorescent bifunctional microspheres

In this paper, we investigated the functional imaging properties of magnetic microspheres composed of magnetic core and CdTe quantum dots in the silica shell functionalized with folic acid (FA). The preparation procedure included the preparation of chitosan-coated Fe3O4 nanoparticles (CS-coated Fe3O4 NPs) prepared by a one-pot solvothermal method, the reaction between carboxylic and amino group...

Template-free synthesis and luminescent properties of hollow Ln:YOF (Ln = Eu or Er+Yb) microspheres

Synthesis and Characterization of Gd2O3 Hollow Microspheres Using a Template-Directed Method

Uniform rare-earth gadolinium oxide (Gd₂O₃) hollow microspheres, as formed through a urea-assisted homogenous precipitation process using carbon spheres as a template and a subsequent heat treatment, were characterized by using X-ray diffraction, Fourier transformed infared spectroscopy, thermogravimetry, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron micr...

Template-Free Fabrication of Bi2WO6 Hierarchical Hollow Microspheres with Visible-Light-Driven Photocatalytic Activity

Highly hierarchical hollow bismuth tungstate (Bi2WO6) microspheres self-assembled by thin nanoplates have been fabricated via a facile template-free solvothermal route. The possible growth pattern and formation mechanism of hierarchical hollow Bi2WO6 microspheres was investigated. The excellent visible-light-driven photocatalytic performance on rhodamine B (RhB) degradation was displayed by hie...
