pH-Responsive Hollow Polymeric Microspheres and Concentric Hollow Silica Microspheres from Silica−Polymer Core−Shell Microspheres

Langmuir, 2008
Nearly monodispersed silica-poly(methacrylic acid) (SiO 2-PMAA) core-shell microspheres were synthesized by distillation-precipitation polymerization from 3-(trimethoxysilyl)propylmethacrylate-silica (SiO 2-MPS) particle templates. SiO 2-PMAA-SiO 2 trilayer hybrid microspheres were subsequently prepared by coating of an outer layer of SiO 2 on the SiO ...

Photons confined in hollow microspheres

Applied Physics Letters, 2001
Incorporation of CdSe quantum dots into a thin (<1 μm) surface shell of polymer microspheres (R∼2–4 μm) is achieved. The room-temperature emission spectra of single, hollow microcavities show several, spectrally well-separated cavity modes in the red-orange spectral range which have been assigned to high-Q whispering gallery modes (WGM) with ...

Dramatic promotion of visible-light photoreactivity of TiO2 hollow microspheres towards NO oxidation by introduction of oxygen vacancy

Applied Catalysis B: Environmental, 2019
Hollow-structured TiO2 has attracted much attention owing to its low density, good light-reflecting ability, and excellent permeability. However, the wide bandgap (about 3.2 eV for anatase TiO2) and fast recombination of photo-generated carriers hamper ...
