example 1

[0008] Example 1: TlI (165.6 mg, 0.5 mmol), V 2 o 3 (18.7 mg, 0.125 mmol), I 2 o 5 (668 mg, 2 mmol) with H 2 O (2 ml) was put into a hydrothermal reaction kettle, mixed evenly, sealed, and placed in a box-type resistance furnace. After 400 min, the temperature was raised from 30 °C to 200 °C, and the temperature was reacted for four days, and finally the temperature was lowered to 30 °C per hour at 3 °C. °C, yellow transparent flaky crystals can be obtained.

Abstract

The invention discloses a nonlinear optical crystal vanadium thallium iodate. The invention discloses a nonlinear optical crystal vanadium thallium iodate. The nonlinear optical crystal vanadium thallium iodate has a chemical formula of Tl (VO2) 2 (IO3) 3 and molecular weight of 894.97, belongs to orthorhombic system and space group Ima2, and has unit cell parameters as follows: a = 14.1143 (17), Angstrom, b=10.2116 (12), Angstrom, C=8.0319 (9), Angstrom, alpha=beta=gamma=90 DEG C, V=1157.6 (2), and Angstrom<3>, Z=4. The nonlinear optical crystal vanadium thallium iodate is prepared by a hydrothermal method. The vanadium thallium iodate [Tl(VO2)2(IO3)3] has excellent nonlinear optical performance, and SHG coefficient of a vanadium thallium iodate powder is similar to that of KTP.

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, optical disc recording, color laser printing, laser projection TV, optical computing and Optical fiber communication, etc., have a series of important applications.
