Embodiment 1

[0036] Mix 0.156g of 2,5-furandicarboxylic acid, 0.101g of potassium nitrate and 0.453g of terbium nitrate in a reaction kettle, then add to 50ml of acetonitrile solution, stir for 10 minutes, and then place it in an oven at 120°C. After 48h, cool to obtain colorless massive crystals, which are green fluorescent materials [Tb 3 K 2 (FDA) 4 (NO 3 ) 3 (MeCN) 2 ] n .

[0037] The following instruments and methods were used to characterize the product: 1. Select a crystal with a size of 0.24×0.23×0.22mm3 for single crystal structure analysis. The single crystal diffraction data was collected on a RigakuSCX diffractometer and monochromated with a graphite monochromator. Mok alpha rays 2.32°≤θ≤28.21°. The obtained compound belongs to the monoclinic crystal system, the space group is C2 / c, and the unit cell parameters are approximately α=90°, β=112.17°, and γ=90°. The crystal structure see figure 1 (Drawing using Diamond software).

Embodiment 2

[0039] Mix 0.312g of 2,5-furandicarboxylic acid, 0.202g of potassium nitrate, and 0.906g of terbium nitrate in a reaction kettle, then add it to 100ml of acetonitrile solution, stir for 10 minutes, and then place it in an oven at 120°C. After 48h, cool to obtain colorless massive crystals, which are green fluorescent materials [Tb 3 K 2 (FDA) 4 (NO 3 ) 3 (MeCN) 2 ] n .

[0040] To the [Tb 3 K 2 (FDA) 4 (NO 3 ) 3 (MeCN) 2 ] n Carry out fluorescence test, which produces 24000a.u. intensity of green fluorescence under the irradiation of 370nm incident light, and the fluorescence spectrum curve is as follows figure 2 Shown.

Abstract

The invention discloses a green fluorescent material and a preparation method of the green fluorescent material. The fluorescent material is named as [Tb3K2(FDA)4(NO3)3(MeCN)2]n, and the molecular formula of the material is C28H14N5O29Tb3K2; the molecular weight is 1439.40, and FDA is 2,5-furandicarboxylic acid. The preparation method of the green fluorescent material comprises the following steps: adding the 2,5-furandicarboxylic acid, terbium nitrate and potassium nitrate into a high-pressure reaction kettle; adding an acetonitrile solution and reacting at 120 DEG C to obtain a block-shaped crystal. The [Tb3K2(FDA)4(NO3)3(MeCN)2]n is illuminated by incident light with the length of 370nm to generate green fluorescent light with the intensity of 24000a.u.. The green fluorescent material and the preparation method of the green fluorescent material have the advantages of simple process, easiness of 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 green 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. They can be used to make luminescent inks, luminescent paints, luminescent plastics, luminescent printing pastes, organic pigments, optical brighteners, photooxidants, coatings, chemistry and biochemistry Analysis, solar traps, anti-counterfeiting marks, drug tracing, lasers and other fields have been more widely used. However, most of the current green fluorescent materials have problems such as poor performance and complicated preparation processes. Summary of the invention [0003] Based on the above-mentioned problems in the prior art, the present invention provides a green fluorescent material and a preparation method thereof, wh...
