A new semi organic non linear optical material, L-valine cadmium chloride (LVCC crystal) has been grown successfully from aqueous solution by the conventional slow evaporation method. The grown LVCC crystal has been characterized by using powder X ray analysis and confirmed the identity of the title compound. The presence of functional groups of the grown crystal has been confirmed by Fourier Transform Infrared Spectroscopy (FTIR) analysis. The optical absorption study was examined by UV-VIS spectrum which indicates a wider optical transmission window for the grown crystal. The UV cutoff wavelength was found out as 220 nm. The work hardening coefficient has been found out as 1.0725, suggests that the given crystal belongs to moderately harder category. It is noticed that SHG efficiency of the grown LVCC crystal is 0.99 times that of the standard KDP crystal.
