Infrared spectroscopy of spherical micromesoporous silica particles at formation and functionalization stages

Spherical micromesoporous particles of amorphous silica with a specific pore surface area to 1600 m2/g were synthesized. The particle inner surface was functionalized by amino groups and luminescent dye molecules chemically bound with them. Particle structure and chemical composition variations at formation and functionalization stages were studied by the IR spectroscopy method.
