PHOTOLUMINOPHOR MIXTURE FOR PRODUCTION OF PHOTOLUMINESCENT FILM OF WHITE LEDS Russian patent published in 2015 - IPC C09K11/08 H01J9/22 H01L33/26 

FIELD: chemistry.

SUBSTANCE: mixture contains binding agent, plasticiser, solvent and powder of photoluminophor of yellow-orange glowing based on cerium-activated rare-earth garnet (ΣLn)₃Al₅O₁₂, where Ln stands for lanthanides, which include yttrium, cerium, gadolinium. Ratio of components is the following, wt %: said photoluminophor powder - 3.0-30.0; binding agent - 3.0-15.0; plasticiser - 0.08-1.0; solvent - the remaining part. Said photoluminophor powder has granulometric composition of crystals in the range from 3 to 20 mcm.

EFFECT: invention makes it possible to obtain composition of photoluminophor mixture for production of photoluminescent film of white light diodes with reduced colour temperature, increased light efficiency and high uniformity of glowing.
