LIGHT CONVERSION FILM CONTAINING COUMARIN GREEN LIGHT DYE

WIPO Patent Application WO/2018/120969

A1

The present invention provides a light conversion film containing a coumarin green light dye, the film containing the green light dye and a cured polymer resin. The molecular structure of the green light dye is as shown in formula (I), wherein R1, R2 and R3 independently represent hydrogen, a C1-C8 substituted or unsubstituted alkyl, alkoxyl or halogen. A test on the photo-physical properties of the green light dye shows that since a molecule having a structure as shown in formula (I) has a high fluorescent quantum yield and a strong light-emitting performance, and is not sensitive to a preparation process, the light conversion film of the present invention has a very stable emission spectrum in the relatively large doping concentration range of the molecule of formula (I) and in the relatively large temperature range.
