[0008] Example 1: Zn(Ac) 2 (50mg, 0.25mmol) with KIO 3 (214mg, 1mmol), H 2 O (2ml) was put into a hydrothermal reaction kettle, mixed evenly, sealed, placed in a box-type resistance furnace, heated from 30°C to 100°C after 360min, and reacted at a constant temperature for 7200min, and finally dropped to 30°C at 3°C ​​per hour. A colorless transparent bulk crystal was obtained.

Abstract

The invention relates to a non-linear optical crystal of iodic acid zinc potassium. The iodic acid zinc potassium has a chemical formula of K2Zn(IO3)4(H2O)2 and the molecular weight of 864.74 and belongs to a monoclinic system; and the iodic acid zinc potassium has a space group C2 and unit-cell parameters are as follows: a is equal to 13.936 (6), b is equal to 7.7609(18), alpha and gamma are both equal to 90 degrees, beta is 126.75(3) degrees and Z is 1. The iodic acid zinc potassium is prepared by using a hydrothermal method. The iodic acid zinc potassium (K2Zn(IO3)4(H2O)2) has excellent non-linear optical performance and the powder second harmonic generation (SHG) coefficient of the iodic acid zinc potassium is 2.3 times that of KDP (KH2PO4) and is equivalent to that of LBO (lithium triborate).

Description

technical field [0001] The invention belongs to nonlinear optical material and its synthesis. Background technique [0002] Nonlinear optical crystals, with frequency doubling effect (SHG), have important application value in high-tech fields such as laser frequency conversion, electro-optical modulation, and photorefractive information processing. Nonlinear optical crystals have attracted extensive attention due to their excellent properties. Nonlinear optical materials are used in modern science and technology, especially in several military and civilian high-tech fields, such as submarine deep-water communication, laser blinding weapons, marine fish detection, CD recording, color laser printing, laser projection TV, optical computing and Optical fiber communication, etc., have a series of important applications. The nonlinear optical crystals currently used in practice include α-LiIO 3 , α-HIO 3 , KIO 3 , KH 2 PO 4 (KDP), KTiOPO 4 (KTP), LiNbO 3 (LNO) and BaTiO ...
