Abstract:Exploring potential nonlinear optical applications, we conducted experimental and theoretical investigations on pristine 4− N,N′-dimethylamino-N′-methyl-4-stilbazolium tosylate (DAST) organic single crystals. Determining structural parameters involved powder Xray diffraction and Rietveld refinement, revealing a monoclinic crystal structure with a noncentrosymmetric and Cc space group for the grown crystal. Additionally, our experimental analysis encompassed Fourier transform infrared (FTIR), ultraviolet−visibl… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
