METHOD OF PRODUCING LANTHANIDE-CONTAINING EPOXY POLYMER Russian patent published in 2020 - IPC C08L63/00 C08L63/02 H01S3/00 

FIELD: chemistry; physics.

SUBSTANCE: invention relates to chemistry, physics and a method of producing novel organometallic polymers, specifically epoxy polymers, and can be used in optics and quantum electronics, primarily for making waveguides, optical amplifiers, lasers. Obtaining lanthanide-containing epoxy resin by mixing epoxy resin with aminomodified silicon dioxide nanoparticles with terbium or ytterbium complexes (lanthanide-containing additive) and hardener at ratio of components based on stoichiometric ratio of resin to hardener and to nanoparticles (weight fractions): epoxy resin – 100, lanthanide-containing additive – 0.5–10, hardener – 21–94. Epoxy resin used is, for example, epoxy-diane resin or epoxy-novolac resin.

EFFECT: invention increases content of lanthanide ions and obtains epoxy polymer with high luminescent properties.
