Purple fluorescent material and preparation method thereof

Abstract

The invention discloses a purple fluorescent material and a preparation method thereof. The preparation method comprises the following step: enabling barbituric acid which has -CONHCO- and COCH2CO- structures and deionized water to perform chemical reaction with cadmium ions which have optical activities so as to prepare a cadmium barbiturate compound with a certain spatial structure, wherein the molecular formula of the compound is C8H10N4O8Cd; the molecular weight is 402.59; a crystal system is orthorhombic; the space group is Ibam; lattice parameters are as follows: a is equal to 12.5498 angstroms, b is equal to 13.967 angstroms, c is equal to 6.9470 angstroms, alpha is equal to 90.00 degrees, beta is equal to 90.00 degrees, and gamma is equal to 90.00 degrees. The compound fluorescent material disclosed by the invention contains rich optical activities and uniquely coordinated and configured Cd (II) ions and nitrogen-containing heterocyclic rings, is beneficial to electron transition and energy transmission, has unique photoelectric activities, shows unique purple fluorescence emission performance, and can be applied as the fluorescent material.

Description

technical field [0001] The invention belongs to the field of material chemistry, and in particular relates to a purple fluorescent material and a preparation method thereof. Background technique [0002] Substances that emit light after being irradiated by ultraviolet rays, X-rays, and electron rays, and stop emitting light quickly after the irradiation stops are called fluorescent substances, and the emitted light is called fluorescence. As early as 1575, it was observed in sunlight that the yellow water solution of Philippine rosewood slices had a very lovely sky blue color. In 1852, when G.G. Stokes observed the quinine and chlorophyll solution with a spectrometer, he found that the wavelength of the light emitted by them was slightly longer than the wavelength of the incident light, so it was concluded that this phenomenon was due to the substance absorbing light energy and regenerating it. Light of different wavelengths is emitted, not due to the diffusion of light. S...

Problems solved by technology

Rare earth complexes such as Eu 3+ , Yb 2+ 、Sm 2+ and Ce 3+ Their luminescence is often observed due to the presence of f-d radiative transitions, especially for Tb 3+ and Eu 3+ The radiative transition of the transition metal falls in the visible region and attracts more attention, but the luminescence of transition metal complexes is less common
