Investigation of internal structure of SiO2 spherical particles by means of small angle neutron and synchrotron radiation scattering.
M.I. Arefev
Photonic crystals and glass, consisting of silica nanoparticles SiO2, have great potential in photonics. As part of the qualification for the degree of Master by means of small angle neutron and synchrotron radiation scattering by the internal structure of particles of SiO2, synthesized by a multistage Stober – Fink – Bohn and photonic crystals and glass grown from them were investigated. Primary particles were found, dependence of order-disorder transition on the SiO2 particle diameter was established, additional subsystem of particles was found, the presence of which is not predicted by any theory of hydrolysis of TEOS.
