Embodiment 1

[0012] Synthesis of Compound Pb by Hydrothermal Synthesis 2 TiOF(SeO 3 ) 2 Cl

[0013] PbCl 2 (166.9 mg, 0.6 mmol), TiO 2 (63.9 mg, 0.8 mmol), SeO 2 (111.0 mg, 1.0 mmol), HF (0.10 mL) and H 2 O (6 mL) was put into a hydrothermal reaction kettle, mixed evenly, sealed, and placed in a box-type resistance furnace. After 600 min, the temperature was raised from 30 °C to 230 °C, and the constant temperature was reacted for 7200 min. °C, colorless rod-shaped crystals can be obtained.

Abstract

The invention relates to a nonlinear optical crystal Pb2TiOF(SeO3)2Cl, its preparation and application. The compound belongs to a monoclinic system, its space group is P21, its cell parameters are a=8.2863(5) angstroms, b=5.3781(2) angstroms, c=10.7167(6) angstroms, beta=111.191(6)<o>, and Z=2. The cell volume V is 445.29 (4) angstrom<3>. The nonlinear optical crystal Pb2TiOF(SeO3)2Cl is prepared by a hydrothermal method. The powder second-harmonic-generation (SHG) coefficient of the Pb2TiOF(SeO3)2Cl is about 9.6 times of that of KDP(KH2PO4).

Description

technical field [0001] The invention relates to a novel nonlinear optical crystal material. 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 crystal 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 , KH 2 PO 4 (KDP), KTiOPO 4 (KTP), LiB 3 o 5 (LBO), β-BaB 2 o 4 (BBO), LiNbO 3 (LNO) and BaTiO 3 (BTO) and so on.
