Description
Technical Field
The invention belongs to the technical field of optical crystal materials, and relates to a iodic acid and cerium phosphate second-order nonlinear optical crystal material, and preparation and application thereof in laser frequency conversion.
Background
The second-order nonlinear optical crystal is a photoelectric functional material widely applied to the laser field, and has important application values in the aspects of laser frequency conversion, photoelectric modulation, laser signal holographic storage, laser communication and the like. The second-order nonlinear optical material which is practically used at present is beta-barium metaborate (beta-BaB)2O4) Lithium borate (LiB)3O5) Potassium dihydrogen phosphate (KH)2PO4) Potassium titanyl phosphate (KTiOPO)4) Lithium niobate (LiNbO)3) Barium titanate (BaTiO)3) Silver gallium sulfur (AgGaS)2) Zinc germanium phosphorus (ZnGeP)2) And the nonlinear optical material applied to the infrared band has defects in properties, so that the elbow is usually applied in practical application. The 3-5 mu m and 8-12 mu m wave bands of the infrared region are taken as atmosphere transmission windows, and the intermediate infrared nonlinear optical material suitable for the wave bands has wide application prospects in the civil fields of laser guidance, infrared remote sensing, medical diagnosis and treatment, laser communication, industrial control and the like; meanwhile, recently, the application demand of the laser in the band in the technical fields of military affairs, such as target tracking and positioning, infrared countermeasure, and the like, is rapidly increased. With the wide application of infrared laser technology and the rapid development of nonlinear optical devices, the current requirements for the physical and chemical properties of infrared nonlinear optical materials are higher and higher, and the current commercialized infrared nonlinear optical crystal materials cannot meet the requirements of practical application. Therefore, the research on novel nonlinear optical crystal materials applicable to the middle infrared is an important direction in the field of current inorganic optical functional materials.
Phosphate as a second-order nonlinear optical crystal has the characteristics of wide band gap, high stability and the like, but has the defect of weak frequency doubling effect. At present, no report on iodic acid phosphate as an infrared nonlinear optical crystal material is found in the literature. The invention is also based on this.

The purpose of the invention can be realized by the following technical scheme:
one of the technical schemes of the invention provides a iodic acid and cerium phosphate second-order nonlinear optical crystal material, the chemical formula of which is Ce (IO)3)2(H2PO4)2。
Further, the crystal material belongs to the orthorhombic system, and the space group is Pna21Cell parameter of
α ═ β ═ γ ═ 90 °, Z ═ 4, and unit cell volume
The crystal structure of the cerium iodate phosphate of the invention is as follows: each Ce4+Ions are coordinated to eight oxygen atoms to form CeO8]Polyhedra in which the four oxygen ligands are derived from four [ IOs ] respectively3]The other four oxygen ligands are derived from four [ H ]2PO4]A group. Adjacent [ CeO ]8]Between polyhedrons via [ IO3]And [ H2PO4]The groups are bridged to form a three-dimensional network structure.
The second technical scheme of the invention provides a preparation method of a iodic acid and cerium phosphate second-order nonlinear optical crystal material, which comprises the steps of firstly mixing a cerium source, an iodine source, phosphoric acid and water to obtain an initial mixture, and then crystallizing under a hydrothermal condition to obtain a target product.
Further, in the initial mixture, the addition ratio of cerium element, iodine element, phosphoric acid and water is1 mmol: (0.5-15) mmol: (0.5-6) mL: (0-5) mL. Preferably, the ratio of cerium element, iodine element, phosphoric acid and water is1 mmol: (2-8) mmol: (1-4) mL: (0-1.5) mL. Here, the amount of water added may be 0mL or not 0, and when the amount of water added is 0mL, it means that water is not added at this time. When no water is added, the reaction medium is phosphoric acid only, and when water is added, phosphoric acid and water together serve as the reaction medium.
Further, the cerium source is cerium dioxide, cerous nitrate or cerous nitrate; preferably, the cerium source is cerium oxide.
Further, the iodine source is periodic acid, iodic acid or diiodo pentoxide; preferably, the iodine source is periodic acid.

Further, the crystallization process is carried out in a closed reaction kettle.
In the crystallization process, phosphoric acid not only provides phosphorus but also serves as a reaction solvent, so the addition amount of phosphoric acid needs to be larger than the stoichiometric ratio of the molecular formula of the product, and the target product cannot be crystallized due to the excessively low addition amount of phosphoric acid. The addition of raw materials is not limited in the scope of the invention, which can lead to the reduction of the yield of the target product and the increase of the yield of byproducts, for example, when the iodine source is excessive, the product is mainly Ce (IO)3)4. The crystallization temperature is defined on the premise that crystals of the target product can be formed, and the target crystals cannot be formed below or above the defined temperature range.
