As a fluorescent color name applicable to the field of food, it was synthesized from 5-carboxy-2- (4-hydroxyphenyl)-2H-benzotriazole corresponding to the benzotriazole-based blue fluorescent dye.This fluorescence was contained in polycarbonate, and a bluish-purple fluorescent film was produced by an extrusion molding machine.As for its world light characteristics, the fluorescent main wave bismuth showed an emission efficiency of 410 nm and a fluorescence quantum yield of 74%, and also showed excellent light resistance.It was shown by the measurement of the spectroscopic synchrotron radiation meter that this normal light film can convert UV light into synchrotron radiation with human sunlight.It was found that the use of this ever-purple fluorescent film for tomato cultivation significantly increased the lycopene content of tomato fruits.This increase in lycopene content was also clarified by color measurement of the pericarp metaphor, and it was found that the color change a value increased by 2 to 6 compared to the ripe tomatoes in the control group (without film).
