plain

Plain fluorescent silica particles are produced by hydrolysis of orthosilicates and related compounds. They have a hydrophilic surface with terminal Si-OH-groups. The fluorescent silica particles are monodisperse and nonporous in the size range of 10 nm to 1,5 µm with a density of 2.0 g/cm³. They have broader size distributions in the area of the porous silica particles with adjusted diameters between 3 and 20 microns and a density of 1.8 g/cm³. The particles are available with red fluorescence (sicastar®-redF, excitation: 569 nm, emission: 585 nm), with green fluorescence (sicastar®-greenF, excitation: 485 nm, emission: 510 nm) or with blue fluorescence (sicastar®-blueF, excitation: 354 nm, emission: 450 nm).
Silica particles with special fluorescent properties are available on request. The particles are delivered in aqueous suspension without any surfactants.
