LIGHT-CONVERTING COMPOSITE POLYMER MATERIAL FOR GREENHOUSES Russian patent published in 2016 - IPC C09K11/08 C08L101/00 C08K3/10 C08K3/28 C08K3/34 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, particularly to polymer composite materials for greenhouses. Light-converting composite polymer material contains a polymer matrix with dispersed therein red inorganic broadband luminophor, which has the formula: Li_s(M_(1-x)-Eu_x)₁Mg_mAl_nSi_pN_q, where m = Sr, Ca, BA, taken separately or together, and where values of indices in elements of the compounds are as follows: 0.045 ≤ s ≤ 0.60, 0.005 ≤ x ≤ 0.12, 0 ≤ m ≤ 0.12, 0 ≤ n ≤ 1.0, 1.0 ≤ p ≤ 2.40, 3.015 ≤ q ≤ 4.20, with restriction concerning all compositions 2.0 ≤ p+n ≤ 2.40 and q ≠ 4. Proposed phosphor converts in red-orange phyto-active radiation within the 580-750 nm not only ultraviolet and, partially, blue-green radiation of sunlight.

EFFECT: technical result consists in stimulation of growth and development of green plants.
