Embodiment 1

[0034] Mix 0.156g of 2,5-furandicarboxylic acid, 0.101g of potassium nitrate, and 0.446g of europium nitrate to form a mixture, add it to 50ml of acetonitrile solution, stir for 10 minutes, and then put it in an oven at 120°C for 48 hours, Cooling to obtain colorless massive crystals, which is the red fluorescent material [Eu 3 K 2 (FDA) 4 (NO 3 ) 3 (MeCN) 2 ] n .

[0035] Use the following instruments and methods to characterize the product: 1. Select crystals with a size of 0.27×0.26×0.24mm for single crystal structure analysis. The single crystal diffraction data are collected on the Rigaku SCX diffractometer and monochromated with a graphite monochromator Mok alpha rays ( ), 3.1°≤θ≤27.5°. The obtained compound belongs to the monoclinic crystal system, the space group is all C2 / c, and the unit cell parameters are approximately α=90°, β=112.05°, γ=90°. The crystal structure of the fluorescent material is shown in figure 1 (drawn using Diamond software).

Embodiment 2

[0037] Mix 0.312g of 2,5-furandicarboxylic acid, 0.202g of potassium nitrate, and 0.892g of europium nitrate, then add it to 100ml of acetonitrile solution, stir for 10 minutes, then put it in an oven at 120°C for 48 hours, then cool A colorless bulk crystal is obtained, which is the red fluorescent material [Eu 3 K 2 (FDA) 4 (NO 3 ) 3 (MeCN) 2 ] n .

[0038] The red fluorescent material [Eu 3 K 2 (FDA) 4 (NO 3 ) 3 (MeCN) 2 ] n Fluorescence test is carried out, which produces red fluorescence with an intensity of 70000a.u. under the irradiation of 395nm incident light, and the result of the fluorescence spectrum curve is as follows figure 2 shown.

Abstract

The invention discloses a red fluorescent material and a method for preparing the same.The red fluorescent material is named as [Eu3K2 (FDA) 4 (NO3) 3 (MeCN)2]n, a molecular formula of the red fluorescent material is C28H14N5O29Eu3K2, a molecular weight of the red fluorescent material is 1418.55, and the FDA represents 2, 5-furan terephthalic acid.The method includes arranging the 2, 5-furan terephthalic acid, europium nitrate and potassium nitrate in a high-pressure reaction kettle; adding acetonitrile solution into the high-pressure reaction kettle; carrying out reaction under the condition of the temperature of 120 DEG C to obtain bulk crystals.Red fluorescent light with the intensity of 70000 a.u.can be generated when the red fluorescent material [Eu3K2 (FDA) 4 (NO3) 3 (MeCN)2]n is illuminated by incident light with the length of 396 nm.The red fluorescent material and the method have the advantages of simple process, easiness in controlling chemical components, good repeatability and high yield.

Description

technical field [0001] The invention relates to the field of fluorescent material preparation, in particular to a red fluorescent material and a preparation method thereof. Background technique [0002] Modern fluorescent materials have become supporting materials in the fields of information display, lighting sources, optoelectronic devices, etc., and can be used to make luminescent inks, luminescent paints, luminescent plastics, luminescent printing pastes, organic pigments, optical brighteners, photooxidants, coatings, chemical and biochemical There are wider applications in areas such as analytics, solar collectors, anti-counterfeiting markers, drug tracers, and lasers. However, the existing fluorescent materials, especially red fluorescent materials, have the problem of poor performance. Contents of the invention [0003] Based on the above-mentioned problems in the prior art, the present invention provides a red fluorescent material and a preparation method thereof,...
