Abstract

The invention provides a third-order nonlinear optical material, namely a tetrabutyl ammonium fullerene ball and a synthesizing method thereof, which belongs to the field of functional materials. The prior inorganic and organic nonlinear optical materials have the problems of easy deliquescence, poor thermal stability, complicated preparation and the like respectively. The molecular formula of the tetrabutyl ammonium fullerene ball provided by the invention is (NH4)18[(C16H36N)4]24[Mo132O372(H2O)72(CH3COO)30].ca.7NH4CH3COO.ca.173H2O. In the method, after {Mo132} and tetrabutyl ammonium bromide are dissolved in water respectively according to the mass ratio of 1 to 42, and are adjusted by acetic acid respectively until the pH value is between 3.5 and 4.5, the {Mo132} and the tetrabutyl ammonium bromide are mixed to obtain the tetrabutyl ammonium fullerene ball. The third-order nonlinear optical material has the advantages of uneasy deliquescence, high thermal stability, larger nonlinear absorption and non-linear refraction coefficient, self-defocusing property and simple preparation.

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 and a synthesis method thereof. Background technique [0002] Nonlinear optical materials have important applications in optical information processing, all-optical switches, optical computing, and optical communications. Third-order nonlinear optical materials are the basis for realizing all-optical switches, optical calculations, and complex phase conjugation. The efficiency of all-optical devices for serial and parallel high-bit-rate data processing depends on the performance of third-order nonlinear materials used for optical signal coupling. . Inorganic crystals are the earliest nonlinear optical materials studied and have been used in the development of devices. However, inorganic nonlinear optical materials have long response time, difficult preparation process, single types of options, and ...
