The purpose is to isolate and purify the plant pigment lycopene contained in dried tomatoes, and apply lycopene to the light emitting layer of organic EL to prepare a green fluorescent thin film. Lycopene was isolated and purified from dried tomatoes by column chromatography, and a light emitting layer of organic EL was formed.
