Novel visible (668 nm) upconversion luminescent YF3:Yb3+/Er3+ nanorice particles and near-infrared (831 nm) upconversion luminescent YF3:Yb3+/Er3+@PAA nanoparticles have been prepared by a simple one-pot method in the absence and presence, respectively, of poly (acrylic acid) (PAA) and have potential applications in biolabeling, especially for in vivo imaging with deep penetration

One-dimensional ZnO:ZnFe2O4 superlattice microwires have been successfully synthesized by an oriented attachment mechanism via a vapor–solid process. Photoluminescence and Raman mapping confirm the presence of the superlattice ZnO:ZnFe2O4 microwire structure, which may find potential applications in future photonic and spintronic devices.

Co3O4 nanobelts with predominantly {011} planes exposed are more active for CO oxidation than Co3O4 nanocubes with exposed {001} planes. The shape and crystal plane effects are highlighted by the fact that the turnover frequency (TOF) of Co3+ sites on {011} planes of Co3O4 nanobelts is far higher than that of Co3+ sites on {001} planes of Co3O4 nanocubes.

Hierarchically nanostructured TiO2 quantum electrodes exhibit good reversibility for direct electrochemistry of cytochrome c and high sensitivity for its detection, and there is a large ionic strength effect on the direct electrochemistry.

Bi2S3 nanostructures with controllable morphology (including nanodots and nanorods) have been prepared via a hot injection technique. The photocatalytic activity and catalysis dynamics of the nanostructured materials are dependent on their morphology.
