Abstract

The invention discloses a fluorescent material with a purple luminescence property and a preparation method thereof. The fluorescent material is characterized in that the fluorescent material is a zinc ethylcarbonate crystal prepared by carrying out a chemical reaction on phenanthroline and quinolinecarboxylic acid having a carboxylic group as well as zinc ions having optical activities, wherein the molecular formula of the zinc ethylcarbonate crystal is C88H64N8O12Zn2, the crystal system of the crystal is monoclinic, the space group of the crystal is P21c, and the cell parameters of the crystal are as follows: alpha is equal to 90 degrees, gamma is equal to 90 degrees, and beta is equal to 97.5650 degrees; and the zinc ion is in a deformed octahedral coordination mode, two nitrogen coordination atoms are derived from phenanthroline, three oxygen coordination atoms are derived from quinoline carboxylic acid, and an oxygen coordination atom is derived from water. The fluorescent material has the advantages of correct space structure and molecular formula, and contains Zn (II) ions with rich optical activities and carboxylic acid with strong coordination capability, thereby being beneficial to electron transition and energy transfer. Thus, the fluorescent material has a good purple luminescence property.

Description

technical field [0001] The invention relates to a fluorescent material, in particular to a fluorescent material with purple luminous performance and a preparation method thereof. Background technique [0002] Fluorescent materials have excellent properties of absorbing ultraviolet rays and emitting visible light, so fluorescent materials have been widely used in various aspects of life. Agricultural light conversion films can be made by adding fluorescent materials to the film, and fluorescent decorative materials can produce novel and peculiar visual effects, so they have been widely used in daily life. Organic fluorescent materials have a wide range of applications in medicine, and can be used to make medical fluorescent probes, so that the site of disease can be easily detected by intracellular imaging. Ultraviolet fluorescent ink can be made by mixing purple fluorescent materials with certain specific chemical components. This ink has outstanding uses in anti-counterfei...
