Abstract: The article was prepared based on the materials of the report at the first All-Russian scientific conference with international participation "YENISEI PHOTONICS – 2020".
Photonic crystals are structures that have a spatial architecture with a periodically changing complex dielectric function at scales comparable to the wavelengths of light in the visible frequency range. The purpose of this study is to obtain three-dimensional photonic crystals by self-assembly from submicron spherical monodisperse particles of polymethylmethacrylate in dispersion media with different viscosities.

Keywords: emulsion-free polymerization, viscosity of dispersion medium, PMMA beads, submicrosphere, self-assembly, 2D and 3D colloidal crystals, photonic crystal, metamaterial, SEM micrographs, IR spectroscopy.
