Synthesis and characterization of colloidal dispersions of fluorescent, monodisperse silica spheres
A. van Blaaderen,Agienus Vrij +1 more
TL;DR: In this article, stable dispersions of colloidal colloidal silica spheres containing a dye or fluorophore have been synthesized according to a general procedure and dispersed in polar and apolar liquids.
Journal ArticleDOI
Monodisperse Colloidal Silica Spheres from Tetraalkoxysilanes: Particle Formation and Growth Mechanism
TL;DR: In this paper, the authors investigated the mechanisms behind the formation and growth of silica particles prepared from tetraalkoxysilanes in alcoholic solutions of water and ammonia, and concluded that the growth proceeds through a surface reaction-limited condensation of hydrolyzed monomers or small oligomers.
Journal ArticleDOI
Synthesis and Characterization of Monodisperse Colloidal Organo-silica Spheres
A. van Blaaderen,Agienus Vrij +1 more
TL;DR: In this paper, a new kind of monodisperse, colloidal silica spheres (organo-silica spheres) were prepared from tetraethoxysilane (TES) in mixtures of ammonia, water, and ethanol.
Journal ArticleDOI
Rare-earth doped polymers for planar optical amplifiers
Lenneke H. Slooff,A. van Blaaderen,Albert Polman,Gerald A. Hebbink,Stephen I. Klink,F.C.J.M. van Veggel,David N. Reinhoudt,J.W. Hofstraat +7 more
TL;DR: In this paper, two different approaches to dope a polymer waveguide with rare-earth ions are presented, one based on organic cage-like complexes that encapsulate the rare earth ion and the other based on Er-doped silica colloidal spheres.
Journal ArticleDOI
Fluorescence Enhancement by Metal- Core/Silica-Shell Nanoparticles**
O. G. Tovmachenko,Christina Graf,Christina Graf,D. J. van den Heuvel,A. van Blaaderen,Hans C. Gerritsen +5 more
TL;DR: Cascade-yellow-labeled, silver-core and carboxyfluorescein-labeling, gold-core nanoparticles with dye-metal distances of 24-25nm exhibit fluorescence enhancement factors as high as 12.5 and 6.8, respectively as discussed by the authors.
