TL;DR: The nonlinear optical single crystals of diglycine barium chloride monohydrate were grown by slow evaporation solution growth technique from the mixture of an aqueous solution of glycine and barium in the ratio 2:1 at room temperature.
Abstract: The nonlinear optical single crystals of diglycine barium chloride monohydrate were grown by slow evaporation solution growth technique from the mixture of an aqueous solution of glycine and barium chloride in the ratio 2:1 at room temperature. The grown crystals were characterized by various techniques such as single crystals X-ray diffraction, FTIR, UV-Vis-NIR spectra, Vickers hardness studies, thermogravimetric analysis, and fluorescence spectra. Its second harmonic generation efficiency was measured by Kurtz and Perry powder technique using Nd:YAG laser.

TL;DR: In this paper, the synthesis, growth and the effect of the position of the substituent in the thienyl ring and also the properties of the======grown chalcone crystals, 2-CTP and 3 -CTP were summarized.
Abstract: This paper summarizes the synthesis, growth and the effect of the
position of the substituent in the thienyl ring and also the properties of the
grown chalcone crystals, 2-CTP and 3-CTP. The formation of compound is
confirmed by the re- corded H1NMR spectra. A FT-IR spectrum confirms the presence of all
functional groups in both of the crystals. Single crystal XRD reports that even
though these two compounds crystallize in monoclinic crystal system, 2-CTP has
centro- symmetric P21/c space group and 3-CTP has
non-centrosymmetric space group P21. Thermal properties of grown
crys- tals analyzed by TG/DTA study explain that the 3-CTP compound is
slightly more stable than 2-CTP. The transparency of these isomers in the vis-IR
region has been studied. Second and third order nonlinear optical properties of
3-CTP and 2-CTP crystals have been investigated by powder SHG and Z-scan
technique respectively.
