Nonlinear optical single crystal of l-Proline trichloroacetate (l-PTCA) was successfully grown by Slow Evaporation Solution Technique (SEST). The grown crystals were subjected to single crystal X-ray diffraction analysis to confirm the structure. From the single crystal XRD data, solid state parameters were determined for the grown crystal. The crystalline perfection has been evaluated using high resolution X-ray diffractometer. The frequencies of various functional groups were identified from FTIR spectral analysis. The percentage of transmittance was obtained from UV Visible spectral analysis. TGA–DSC measurements indicate the thermal stability of the crystal. The dielectric constant, dielectric loss and ac conductivity were measured by the impedance analyzer. The DC conductivity was calculated by the cole–cole plot method.

In this article we are reporting the bulk growth of l-PTCA by SEST method. The grown single crystal is subjected to different characterization for complete analyses in order to know its suitability for device fabrications. High resolution XRD have measured in order to know the perfection of the crystal. Optical constants and solid state parameters are calculated at first time. DC conductivity is determined by cole–cole plot from impedance analysis first time.Figure optionsDownload as PowerPoint slide
