Title:
RARE EARTH METAL COMPLEX, INK COMPOSITION USING THE SAME AND FLUORESCENT LABELING AGENT
Document Type and Number:
Japanese Patent JP2009292748
Kind Code:
A
Abstract:
To provide a rare earth metal-based luminescent material that forms various metal ion complexes exhibiting fluorescent colors being the three primary colors of red, green and blue by using the same ligand.
The rare earth metal complex is represented by general formula (1) (wherein Ln is yttrium or a lanthanoide metal; M is a monovalent cation; and X is an acetate ion or the like) coordinated with ethylenediaminetetraacetic acid and 5-formylsalicylic acid prepared by the reaction formula.
