Abstract

The invention relates to an inorganic compound with a non-heart structure, and a preparation method and an application thereof as a nonlinear optical crystal. The crystal has a chemical formula of K2Au(IO3)5, belongs to an orthorhombic crystal system, has a space group of C[mc]2[1], and has crystal cell parameters of a=11.5949(8) angstroms, b=11.6905(6) angstroms, c=11.4716(6) angstroms, alpha=beta=gamma=90 DEG and Z=4. The yellow K2Au(IO3)5 crystal is prepared by a hydrothermal method. The powder frequency-doubling effect of the K2Au(IO3)5 crystal is 1.0 time that of KTiOPO4.

Description

technical field

[0001] The invention relates to a novel nonlinear optical crystal material. Background technique

[0002] Nonlinear optical crystals are a class of functional materials widely used in the field of optoelectronic technology, which can realize laser frequency conversion, modulation of laser intensity and phase, and holographic storage of laser signals. At present, the research on inorganic nonlinear optical materials mainly focuses on borate, phosphate, iodate and other systems, such as the commercial nonlinear optical crystal KH 2 PO 4 (abbreviated as KDP), KTiOPO 4 (abbreviated as KTP), LiB 3 o 5 (abbreviated as LBO), β-BaB 2 o 4 (abbreviated as BBO), α-LiIO 3 Wait. Among them, the iodate system due to the asymmetric IO in the structure 3 Cells contain lone pairs of electrons and often exhibit extremely strong nonlinear optical effects, attracting extensive research interest. In recent years, researchers will have distorted MO 6 d of the octahedral...
