ABSTRACT Picric acid with Succinic acid resulting the Succinic picrate crystals doped with copper sulphate of (0.1M) has been reported already in this journal . The present study investigates the change in spectral and optical properties of the synthesized crystal when the concentration of the dopant copper sulphate has been increased. Succinic-Picrate crystals are synthesized in equi molar proportions of picric acid and succinic acid and incorporating a concentration of (0.2M) copper sulphate 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 2theta values 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 powdered pattern of XRD has been indexed using Chekcell software.
