Growth and characterization of inosine crystals: a third order NLO single crystal

Abstract

A organic single crystal of Inosine have been grown from saturated solution by slow evaporation solution growth technique. The crystalline perfection of the grown crystal was accomplished by Single X-ray diffraction studies. The as grown single crystal exhibit monoclinic structure type, crystallizes in the space group of P2_1. The various functional groups present in the crystal was analyzed by FT-IR and FT-Raman studies. The optical transmission window of the grown crystal was found by UV–vis-NIR analysis. Thermogravimetric (TG) and differential thermal analysis (DTA) were carried out to characterize the thermal stability of the grown crystals. Theoretical vibraitonal frequencies are calculated from DFT-B3LYP gradiant calculations employing 6–31G(d,p) as a basis set. These datas are in good agreement with theoretical and experimental values of FT-IR, FT-Raman and UV–vis-NIR measurements. Third order nonlinear optical efficiency was examined using Z-scan technique.
