Problems solved by technology

At present, macromolecular complexes are mostly synthesized by direct coordination between macromolecular ligands and rare earth metal ions. This method will lead to insufficient coordination numbers of rare earth ions, and it is difficult for macromolecular ligands to achieve energy level matching with different rare earth ions at the same time, resulting in Luminous performance is poor

Abstract

The invention relates to a preparation method of europium terbium zinc containing warm white macromolecule complex fluorescent powder, which comprises the following steps: firstly, respectively preparing to obtain a macromolecular ligand poly(p-VBA-MMA) and three primary colors of small-molecular vacancy complexes Eu(TTA)2phen, Tb(p-BBA)3 and Zn(BTZ); then carrying out coordination on the macromolecular ligand and the three primary colors of small-molecular vacancy complexes so as to prepare the europium terbium zinc containing warm white macromolecule complex fluorescent powder. The method disclosed by the invention is simple in preparation process and accurate in data, the warm white fluorescent powder has a good luminescence property; under the excitation of 365 nm ultraviolet light, color coordinates of the warm white fluorescent powder are that x being equal to 0.39 and y being equal to 0.35; the warm white fluorescent powder is the europium terbium zinc containing macromolecule complex warm white fluorescent powder with the good luminescence property.

Description

technical field [0001] The invention relates to the technical field of preparation and application of luminescent materials, in particular to a method for preparing a warm white macromolecular complex fluorescent powder containing europium and terbium zinc. Background technique [0002] Near-ultraviolet white light LED has the characteristics of high color rendering, high rendering index and controllable light color, and has become the first choice for LED lighting. Near-ultraviolet excited phosphor is the decisive factor for LED luminous performance. Macromolecular complexes have become a research hotspot for near-ultraviolet excited phosphors because of their excellent luminescence properties of rare earth complexes, excellent mechanical properties of polymers, and easy processing characteristics. At present, macromolecular complexes are mostly synthesized by direct coordination between macromolecular ligands and rare earth metal ions. This method will lead to insufficient...
