Abstract

The invention discloses a one-dimensional coordination polymer with matching SHG performance and a synthesis method thereof, and relates to the field of second-order nonlinear materials. The powder X-ray diffraction peak position of the coordination polymer material is as follows: 6.76°± 0.50°, 8.77°±0.50°, 10.15°±0.50°, 10.30°±0.50°, 11.43°±0.50°, 13.44°±0.50°, 13.81°±0.50°, 16.04°±0.50° and other specific peaks; 2θ angle The range is between 5°‑35°. The coordination polymer provided by the present invention not only has excellent SHG performance, but also has phase-matching performance. The phase-matching performance has stronger application significance for the application of second-order nonlinear materials, so that the polymer has a wider application range and good application prospects.

Description

technical field [0001] The invention belongs to the field of second-order nonlinear materials with phase-matching properties, and specifically relates to the field of coordination polymers of second-order nonlinear materials with phase-matching properties. Background technique [0002] Nonlinear optics is a branch of modern optics, which studies the nonlinear phenomena and applications of media under the action of strong coherent light. The study of nonlinear optics is of great significance to the development of laser technology, spectroscopy, and material structure analysis. Applications of nonlinear optics range from technical fields to research fields. For example: using various nonlinear crystals to make electro-optical switches and realize laser modulation. The tuning of laser frequency is realized by optical parametric oscillation. Combined with frequency doubling and frequency mixing technology, it can be tuned in a wide range from mid-infrared to vacuum ultraviole...
