Abstract

The invention relates to quaternionic rare earth organic complexes as shown in general formula (I). The chemical name of the organic complexes is Eu-Tb thenoyltrifluoroacetone-N-phenylanthranilic acid-o-phenanthroline organic complexes. The chemical formula of the organic complexes is Tb1-xEux (TTA) 2 (N-HPA) Phen, wherein x is equal to 0-1. The invention also relates to a method for making the quaternionic rare earth organic complexes.

Description

technical field [0001] The invention relates to the technical field of rare earth organic luminescent materials, in particular to a quaternary rare earth organic complex and a synthesis method thereof. The quaternary rare earth organic complex has photoluminescence and electroluminescence properties. Background technique [0002] Rare earth luminescent materials can be divided into photoluminescence, cathodoluminescence, X-ray luminescence, and electroluminescence materials, etc., and have great application value in the fields of laser, photoluminescence, and electroluminescence complexes. [0003] According to the luminescence principle of rare earth complexes, the structure and properties of ligands are important factors affecting the luminescence efficiency of rare earth complexes, and it is very important to design and synthesize new ligands with high-efficiency sensitized luminescence. Bisβ-diketones containing polyaromatic rings can not only absorb ultraviolet light e...
