Abstract
Crystals of urea l-malic acid (ULMA) were grown by solvent evaporation technique at ambient temperature using different solvents like water, methanol and ethanol. For identification of elements present in ULMA crystal, CHN test was carried out followed by characterization like XRD, optical transmission, SHG efficiency measurement and dielectric studies. A remarkable morphological change was observed for crystals grown from different solvents. But XRD studies did not reveal any change in lattice parameters for these ULMA crystals. Optical transmittance was found to be increased for crystals grown from water. Both the dielectric constant and dielectric loss vary slowly with frequency.
