Embodiment Construction

[0012] 1. Preparation of compounds

[0013] Weigh an equimolar amount of p-cyanobenzoic acid (4-Hcba) and sodium hydroxide (NaOH), add it to a beaker with an aqueous solution, stir to allow it to fully react, then heat it to about 80°C, and evaporate the water to dryness. The sodium salt of p-cyanobenzoic acid (Na(4-cba)) is obtained.

[0014] Weigh ZnBr 2 (1.0mmol), Na(4-cba)(0.5mmol) and NaN 3 (1.0mmol), add 15mL of distilled water, put it into a closed 25mL reaction kettle, raise the temperature to 130-140°C, keep the temperature constant for 3 days, and then cool down to room temperature at a rate of 1°C / hour to obtain crystals. Through X-ray single crystal diffraction analysis, it is determined that the crystal is [Zn(N 4 CC 6 h 4 COO)].

[0015] 2. Performance test

[0016] We tested the optical properties of the obtained 5-benzoic acid-zinc tetrazolium complex, and its second-order nonlinear optical effect was about 2.5 times that of KDP. The relationship curve ...

The materials can be applied to manufacturing a secondary harmonic generator, an upper frequency converter, a lower frequency converter and an optical parametric oscillator, and can be used for storing and restoring information, transmitting optical information, image display, as well as storing holograph of a paginating device and a ferroelectric light valve array in holograph photographing.

Description

technical field [0001] The invention relates to a complex formed by a nonlinear optical and ferroelectric material 5-benzoic acid-tetrazolium ligand and zinc (molecular formula: C 8 h 4 N 4 o 2 Zn) preparation and application. Background technique [0002] Ferroelectric material is a kind of multifunctional material with properties of ferroelectricity, piezoelectricity, pyroelectricity, electro-optic and nonlinear optics at the same time. The so-called ferroelectric material refers to a material whose crystal structure has spontaneous polarization when no external electric field is applied, and the direction of its spontaneous polarization can be reversed or reoriented by an external electric field. This property of the material is known as "ferroelectricity" or "ferroelectric effect". In recent years, ferroelectric materials have developed extremely rapidly and have been widely used in electronic technology, laser technology, infrared detection technology, ultrasonic (...
