Embodiment 1-4

Embodiment 1

[0032] At room temperature, put 10mmol of manganese chloride and 10mmol of dibromo-1,4-dibutyl-1,4-diazabicyclo[2.2.2]octane into a beaker respectively, at 10~15ml / min Slowly add distilled water and stir to dissolve. The volume of distilled water is 10mL, and then the two beakers are mixed with each other. After stirring evenly, stand at room temperature for 4 days to obtain the compound C with fluorescent properties. 14 h 30 N 2 Cl 4 Mn.

Embodiment 2

[0034] At room temperature, put 20mmol of manganese chloride and 10mmol of dibromo-1,4-dibutyl-1,4-diazabicyclo[2.2.2]octane into a beaker respectively, at a rate of 10-15ml / min Slowly add distilled water and stir to dissolve. The volume of distilled water is 10mL, and then the two beakers are mixed with each other. After stirring evenly, stand at room temperature for 5 days to obtain the compound C with fluorescent properties. 14 h 30 N 2 Cl 4 Mn.

Abstract

The invention discloses a divalent manganese fluorescent material based on dibromo-1,4-dibutyl-1,4-diazabicyclo[2.2.2]octane, which belongs to the molecular ion-based divalent manganese fluorescent material. The chemical formula of the fluorescent material is C14H30N2Cl4Mn. At a temperature of 296K, the crystals belong to the orthorhombic system and the space group Pbcn. It's weird to mix soluble salts containing Mn2+ and triethylenediamine derivatives to self-assemble with the natural volatile solvent of the solution. The invention is a green fluorescent compound, the material used in the preparation process is simple, easy to operate, sufficient source of raw materials, low production cost, high yield and good repeatability; the thermal decomposition temperature point is relatively high, and the crystal particles are uniform.

Description

technical field [0001] The invention belongs to the field of fluorescent materials, in particular to a divalent manganese fluorescent material based on dibromo-1,4-dibutyl-1,4-diazabicyclo[2.2.2]octane and its preparation method and application , the fluorescent material has green light emission under the excitation of ultraviolet light. Background technique [0002] Phosphor powder, commonly known as luminous powder, is usually divided into two types: photo-induced energy storage luminous powder and radioactive luminous powder. Photo-energy storage luminous powder is a fluorescent powder that stores light energy after being irradiated by self-identified light, daylight light, and ultraviolet light, and then slowly releases it in the form of fluorescence after stopping the irradiation, so it can be seen at night or in the dark. The light can still be seen. [0003] Light emitting diode (Light emitting diode, LED) is an energy conversion device that can convert electric ene...
