Picric acid with Diphenyl amine resulting the Diphenyl amine picrate crystals exhibit the nonlinear optical properties, which is an important parameter in laser optics.Acetamide-Picrate crystals are synthesized in equi molar proportions of picric acid and Diphenyl amine by slow evaporation technique. The grown crystals are investigated by various spectral techniques like FTIR Spectroscopy, U.V Spectroscopy. It is examined using the XRD Studies powdered pattern.The well-defined peaks at specific 2thetavalues show high crystallinity of the grown crystals. The values of hkl, relative intensity and 2 theta values for the reflection peaks of the powder XRD pattern are given. The crystals have wide transparency between 200 to 1100nm. The recorded transmission is almost above 95% throughout the region. This is the most desirable property of the crystals used for nonlinear optical application. The Diphenyl amine picrate crystals are studied for its unit cell measurements by taking Single Crystal XRD measurements. SEM-EDAX studies are also carried out to study the morphology of the crystals.
