Abstract Single crystal of organic nonlinear optical material 3-(4-Fluorophenyl)-1-(4-methoxyphenyl) (FMP) was grown with the help of single walled glass ampoule in vertical Bridgman technique. The structural analysis confirmed the cell parameters and crystallinity of the single crystal with the space group of Pbca. The presences of desired components in the single crystal were confirmed by the NMR spectrum. The lower cut off wavelength of the single crystal was observed at 423 nm from the absorption spectra of the single crystal. The electrical property of grown single crystal was studied by measuring the dielectric constant and dielectric loss. The surface hardness test and amount of damage caused by incident laser beam on the surface of the single crystal determined the mechanical strength of the crystal. The FMP single crystal was found to exhibit negative photoconductive nature. The etch pit density and non-linear optical properties were determined by etching measurement and by observation of green light in Kurtz-Perry powder method. The grown crystal was studied thermal stability and melting point with TGA-DSC analysis.
