Single crystals of new organic nonlinear optical material urea L-valine were grown by slow eveporation solution growth technique at room temperature.Elemental compostion percentages were analysed using CHN study. Crystalline nature of the sample was confirmed by powder XRD. A functional group present in the crystal was identified using FT-IR spectral analysis. An optical transmittance study was also carried out for the crystal. Dielectric studies were performed with respect to temperature at various frequencies (50Hz-5MHz). Photoconductivity study reveals the negative photoconductivity nature of the crystal. Powder second generation efficiency of the crystal was studied using modified kurtz and perry technique.
