The application as a rare earth europium complex and a luminescent material

摘要

This invention regards application as a rare earth europium complex and a luminescent material. Constitutional formula of the aforementioned europium complex Eu (ND) is _{xA yL m}, here, ND is the 4 hydroxy 1,5 nahuchirijin anionic ligand, A is the other anionic ligand, L is the neutral ligand, x=1, 2 or 3, y=0, 1 or 2, at the same time is x+y=3, m=0, 1, 2 or 3 is. This kind of europium complex the photo luminescence quantum efficiency whose efficiency is high, the heat which is superior cheaply has had Characteristic and satisfactory carrier carrying efficiency, it can use as photo luminescence and the electro- luminescence material.
