Abstract
The invention discloses an organic-inorganic hybridization three-order non-linear optical crystalline material and a preparation method thereof. The crystalline material is giant wheel-shaped nanometer polyacid crystal modified in glutamic acid, and a molecular formula is Na2Gd4[Mo126Mo28O462H14(H2O)42(HOOCCH2CH2CH(NH3+)COO-)14]ca.300 H2O. The preparation method comprises the following steps of: mixing aqueous solution of GdCl3 and aqueous solution of Na2MoO4 to generate white precipitates with stirring, and performing suction filtration on the white precipitates and washing with water; dissolving L-sodium glutamate in hydrochloric acid solution, adding the white precipitates and hydrazine hydrochloride into the hydrochloric acid solution of the L-sodium glutamate sequentially, heating ina water bath at the temperature of 70 DEG C for 3 hours, cooling the solution to room temperature and filtering to obtain blue square crystals after 3 days, filtering, washing the obtain solids, and airing naturally to obtain the crystalline material, wherein a molar ratio of the hydrazine hydrochloride to the L-sodium glutamate is 1:9.4. The optical crystalline material has large non-linear absorption coefficients and non-linear refraction coefficients and self-focusing performance, and is stable at the normal temperature, readily available in raw materials and high in yield, and a syntheticmethod is simple.
