Problems solved by technology

However, due to the absence of f—f configuration transitions in common boronyl groups and weak light absorption ability, the molar absorption coefficient is usually less than 1 M-1cm-1, Therefore, it is almost impossible to cause its luminescence by directly exciting the boronyl group.

Embodiment Construction

[0014] 1. Preparation of compounds

[0015] Weigh boric acid (H 3 BO 3 ) 0.062 to 1.240g, 1,4-butanediamine (C 4 h 12 N 2 ) 0.2 to 2g, water (H 2 O) 0.5 to 20ml, the molar ratio is 1~20:0.23~23:2.7~55, stir for 1~20min, put it into a closed 28mL reaction kettle, heat up to 100~250℃, keep the temperature for 2~500h, Cooling rate is 1~50 ℃ / hr, cool down to room temperature, filter, wash with distilled water and air dry naturally to get C 4 h 17 N 2 B 7 o 13 blocky transparent crystals. After X-ray single crystal diffraction analysis, it was determined that the crystal was C 4 h 17 N 2 B 7 o 13 .

[0016] According to its specific reactant implementation examples of the above-mentioned preparation method are as follows: according to the molar ratio:

[0017] (1)H 3 BO 3 :C 4 h 12 N 2 :H 2 O=1:2:2.7,

[0018] (2)H 3 BO 3 :C 4 h 12 N 2 :H 2 O=2:20:55,

[0019] (3)H 3 BO 3 :C 4 h 12 N 2 :H 2 O=1:20:2.7,

[0020] (4)H 3 BO 3 :C 4 h 12 N 2 :...

The organic amine template borate fluorescent material is obviously enhanced in luminous intensity by obtaining a crystal by adopting hydrothermal reaction and carrying out heating treatment on the crystal. The molecular formula of the compound is C4H17N2B7O13, the space group of the compound is P-1(No.2), the unit cell parameters are as follows: a=8.8769(3), b=9.3204(2), c=10.2204(5), a=74.474 (2), beta=85.292 (5), g=72.730 (2), Z=4, and the unit cell volume V=778.01(5)<3>. The organic amine template borate fluorescent material disclosed by the invention is used for manufacturing a fluorescent luminous device.

Description

technical field [0001] The invention relates to an organic amine template borate fluorescent material and its preparation method and application. Background technique [0002] Due to the unique coordination structure (triangle and regular tetrahedron) of boron element and its flexible coordination number (3 and 4), boron oxide polyanions with various structures can be formed. Borates play an important role in functional materials such as luminescent materials, second-order nonlinear optical materials, refractory materials, magneto-optical storage materials, and hydrogen storage materials, especially borate luminescent materials. The luminescence of organic matter is also one of the most researched directions at present. Vivian Wing-Wah Yam and others have studied the energy level of organic matter, showing that organic matter containing nitrogen has good photoexcitation, photoluminescence and thermoluminescence properties. , can be used in high-density optical disc storage ...
