Synthesis, crystal growth and characterization of a novel semi-organic p-toluidine cadmium chloride single crystal for nonlinear optical (NLO) applications

A novel single crystal of p-Toluidine cadmium chloride was examined by X-ray diffraction analysis which revealed the structural data, cell parameters and crystal system. The PTCC crystal is grown in the 1:1 ratio by slow evaporation solution growth technique. The UV–visible spectrum analysis observed the optical quality of the crystal in the range of 200 nm to 1000 nm. The grown crystal shows a good transmittance range. The identification of various functional groups of PTCC crystal was analysed by Fourier Transform Infrared Spectroscopy. The photoconductivity study analysed the grown PTCC crystal has a photoconductivity nature. The dielectric constant and dielectric loss are measured as a function of frequency used to determine the electrical properties. The thermal analysis of both thermogravimetric and differential thermal study measures a material is stable up to 150 °C. The third-order nonlinear susceptibility (χ3) is calculated by the z-scan technique whose wavelength is 632.8 nm using a source of He–Ne laser.
