Abstract

Disclosed are molybdenum oxide base third-order nonlinear optical materials and a synthetic method thereof, which belong to the field of function materials. Existing inorganic nonlinear optical materials and organic nonlinear optical materials have the problems that the materials are easy to deliquesce, poor in heat stability, small in nonlinear coefficient and the like. According to the novel materials, each of anions is in a spherical structure and is represented by the molecular formula of (NH4)42[{(MoVI)MoVI5O21(H2O)6}12{MoV2O4}30(CH3COO)5(HOOC(CH2)2COO)25] =100H2O. According to the molybdenum oxide base third-order nonlinear optical materials, ammonium succinate is added into a {Mo132Ac} aqueous solution in a ratio of 1:40, stirred, acidized with HCI, rested and crystallized, so that the novel materials are obtained. The third-order nonlinear optical materials are easy to prepare and not likely to deliquesce, have no obvious nonlinear absorption property under the effect of 5ns laser pulses with the laser wavelength of 532nm, and have a large nonlinear refraction coefficient and the self-defocusing property.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to an organic-inorganic hybrid third-order nonlinear optical material with a Mo-O-based spherical structure and a synthesis method thereof. Background technique [0002] With the development of laser weapons, laser protection becomes more and more urgent. The existing laser protection materials are based on the principle of linear optics. The laser protection glasses made, whether absorbing, reflecting, or composite, have single protection wavelength, low transmittance, and protection angle requirements. And other shortcomings, most of them can only play a protective role on a small number of specific wavelengths, and some can only play a protective role on one wavelength. Nonlinear optical protection is an inevitable trend to meet these challenges. [0003] Inorganic crystals are the earliest nonlinear optical materials studied and have been used in the development...
