[0008] Example 1: PbCl 2 (50mg, 0.182mmol), I 2 o 5 (200mg, 0.599mmol) and La 2 o 5 (50mg, 0.153mmol), H 2 Put O (2ml) into a hydrothermal reaction kettle and mix evenly, seal it, place it in a box-type resistance furnace, heat up from 30°C to 200°C after 1200min, react at a constant temperature for 5760min, and finally lower it to 30°C at 6°C per hour. A colorless transparent bulk crystal was obtained.

Abstract

The invention relates to nonlinear optical crystal plumbum-lanthanum iodate which belongs to a nonlinear optical material and synthesis thereof. The plumbum-lanthanum iodate has a chemical formula of La3Pb3O(IO3)13 and the molecular weight of 3328, belongs to the trigonal system and has a space group of R3c and unit cell parameters that a is 22.234(2), b is 22.234(2), c is 13.702(1)*, Alpha and Beta are respectively 90 degrees, Gamma is 120 degrees, V is 5866(1)*3 and Z is 6. The plumbum-lanthanum iodate (La3Pb3O(IO3)13) is prepared by a hydrothermal method and has good nonlinear optical performance, and the SHG coefficient of plumbum-lanthanum iodate powder is two times of that of KDP and equivalent to that of LBO.

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 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. 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 3 (BTO) and so on. Among them, iodate nonlinear optical crystals have attracted extensi...
