Embodiment 1-4

Embodiment 1

[0031] At room temperature, put 10mmol of manganese chloride and 10mmol of dibromo-1,4-diethyl-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 4 days to obtain the compound C with fluorescent properties. 10 h 22 N 2 Cl 4 Mn.

Embodiment 2

[0033] At room temperature, put 20mmol of manganese chloride and 10mmol of dibromo-1,4-diethyl-1,4-diazabicyclo[2.2.2]octane into a beaker, slowly at a rate of 5ml / min 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. 10 h 22 N 2 Cl 4 Mn.

Abstract

The invention discloses preparation, representation and application of a divalent manganese fluorescent material based on dibromo 1, 4-diethyl-1, 4-diazabicyclo [2, 2, 2] octane. A chemical formula of the fluorescent compound is C10H22N2Cl4Mn. At temperature of 296K, and crystals belongs to an orthorhombic crystal system, and P212121 chiral space group; the divalent manganese fluorescent material is prepared by mixing soluble salt containing Mn2+ and a triethylene diamine derivative and adopting a solution natural volatilization solvent for self-assembly. The green fluorescent compound is simple in material preparation process, easy to operate, sufficient in raw material source, low in production cost, high in yield and repeatability, relatively high in thermal decomposition temperature point and uniform in crystal particle.

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-diethyl-1,4-diazabicyclo[2.2.2]octane and its preparation method and application , the divalent manganese fluorescent material has green light emission under the excitation of ultraviolet light. Background technique [0002] Fluorescence, also known as "fluorescence", refers to a cold luminescence phenomenon of photoluminescence. When a substance at room temperature is irradiated by incident light of a certain wavelength (usually ultraviolet or X-ray), it absorbs light energy and enters an excited state, and immediately de-excites and emits outgoing light with a wavelength longer than that of the incident light (usually at a wavelength of Visible light band); and once the incident light is stopped, the luminescent phenomenon will disappear immediately. [0003] Phosphor powder, commonly known as luminous powder,...
