Embodiment 1

[0054]Example 1: Mix 0.3 g of terbium nitrate hexahydrate, 0.04 g of trimesic acid and 2 ml of N-methylpyrrolidone, and stir at 60 degrees Celsius for 5 minutes. After the particles are dissolved, filter with 0.22 micron pores. Filter the solution through a filter to remove possible particles. Use a femtosecond laser with a wavelength of 532 nm, a repetition rate of 80 MHz, and a pulse width of less than 170 femtoseconds, after focusing by a 100x, NA1.4 objective lens. After conversion, when the laser energy density is 9.3×105W / cm2, the substrate is first exposed for 100 milliseconds, and then the energy density of 4.5×105W / cm2 is exposed for 200 milliseconds. At this time, a 350-nanometer diameter can be grown on the substrate. For MOFs microstructure materials, with the increase of exposure time under the energy density of 4.5×105W / cm2, the diameter of MOFs microstructure materials will gradually increase and finally reach a maximum value of about 4.5 μm.

Embodiment 2

[0055] Example 2: Mix 0.01 g of zinc nitrate tetrahydrate, 0.03 g of imidazole and 3 ml of N,N-dimethylformamide, stir for 5 minutes to dissolve the particles, and filter the solution again using a 0.22-micron pore filter, Filter out possible particles. Use a femtosecond laser with a wavelength of 532 nm, a repetition rate of 80 MHz, and a pulse width of less than 170 femtoseconds, and focus through a 100x, NA1.4 objective lens. After conversion, when the laser energy density is 6.2×105W / cm2, the substrate is first exposed for 100 milliseconds, and then exposed at the energy density of 3.2×105W / cm2 for 100 milliseconds. For MOFs microstructure materials, as the exposure time increases at an energy density of 3.2×105W / cm2, the diameter of the MOFs microstructure materials gradually increases and finally reaches a maximum value of about 6 microns.

Abstract

The invention belongs to the field of laser manufacturing, and more particularly relates to a metal organic framework microstructure laser manufacturing device and method. The laser manufacturing device focuses the laser on the interface containing the raw material solution required for the synthesis of the metal organic framework and the integrated substrate of the metal organic framework microstructure. The solution is irradiated by the laser, and the metal organic framework material will grow at the focal point of the laser. thereby sticking to the substrate. By relatively moving the position of the laser focus, one-step synthesis and integration of the metal-organic framework microstructure can be realized on the designated position of the substrate. By adjusting the parameters of the laser, the crystal form, size and doping of the synthesized metal organic framework can be adjusted. The method of the invention realizes the synthesis and integration of the metal-organic framework microstructure in one step through the method of laser manufacturing. The invention can realize the precise integration of the position, and solve the problems of performance degradation and difficulty in realizing the precise integration of the position in the separation and transfer process in the prior art.

Description

technical field [0001] The invention belongs to the field of laser manufacturing, and more particularly, relates to a device and method for laser manufacturing of metal-organic framework microstructures. Background technique [0002] Metal-Organic Frameworks (MOFs) are organic-inorganic hybrid materials with intramolecular pores formed by the self-assembly of organic ligands and metal ions or clusters through coordination bonds. In MOFs, the arrangement of organic ligands and metal ions or clusters has obvious directionality, which can form different framework pore structures, thus exhibiting different adsorption properties, optical properties, electromagnetic properties, etc. MOFs show great development potential and attractive development prospects in modern materials science. [0003] At present, the preparation of metal-organic framework materials usually adopts the method of chemical synthesis. In this method, the raw materials required for synthesizing the metal-orga...
