FIELD: nanotechnology.
SUBSTANCE: invention relates to nanotechnology and can be used to change effectively the optoelectronic properties of ensembles of silver nanoparticles coated with ligand shell in viscous media and films. The invention can be used to create photonic crystals, optical filters and a new generation of Raman lasers. For obtaining highly ordered assemblies of silver nanoparticles with a ligand shell in high-viscosity aqueous solution of polyvinyl alcohol or gelatin 3.6 mmol/g of silver nitrate solution, 15 mmol/g of sodium oleate and 10 mmol/g of sodium borohydride are added. The reaction proceeds without stirring.
EFFECT: invention enables to obtain high-viscosity media and films assemblies of nanoparticles coated with a ligand shell with low degree of aggregation.
