DISPERSION CONTAINING DOPED EU2+ INORGANIC LUMINESCENT NANOPARTICLES FOR USE IN GREENHOUSES AND SHEET STRUCTURES, AS WELL AS COATINGS FOR GREENHOUSES CONTAINING SUCH NANOPARTICLES Russian patent published in 2025 - IPC C09K11/77 C09K11/02 A01G9/14 B32B33/00 C03C17/00 G02B5/20 

FIELD: nanotechnology.

SUBSTANCE: invention relates to a dispersion of luminescent nanoparticles for coating a greenhouse glazing structure. Dispersion contains: an organic or aqueous medium and luminescent nanoparticles, where the nanoparticles contain or essentially consist of doped particles with Eu²⁺ SiAlON, where concentration of Si ranges from 31 at.% to 33 at.%, concentration of Al is from 0.3 at.% to 4 at.%, concentration of O is from 63 at.% to 66 at.%, concentration of N is 0 at.% and Eu²⁺ is from 0.3 at.% to 1 at.%. Also disclosed is a transparent polymer sheet for a greenhouse, a luminescent glazing structure for a greenhouse and a greenhouse containing said nanoparticles.

EFFECT: luminescent nanoparticles SiAlON:Eu²⁺ have strong absorption in the UV region and emission in the API region and do not overlap or at least almost do not overlap with the absorption region, wherein the quantum efficiency of luminescence (QEL) is close to one; in addition, nanoparticles have excellent properties in terms of durability, including, for example, chemical stability, thermal stability, hardness and colour stability.
