Study of optical, thermal and mechanical properties of trisglycine zinc chloride: A semiorganic non-linear optical single crystal

J. Uma and V. Rajendran

Abstract

Single crystals of semi organic material Trisglycine zinc chloride (TGZC) were grown from aqueous solution by slow evaporation solution growth technique. Single crystal X-ray Diffraction analysis was used to estimate the cell parameters of the grown crystals. The grown crystals were tested by FTIR, thermo gravimetric and differential thermal analysis and UV–vis–NIR analysis. The absorbance spectrum of TGZC crystal is used to calculate the band gap and it is found to be 4.93eV. The second harmonic conversion efficiency of TGZC was determined using the Kurtz and Perry powder technique. It was observed to be 0.5 times greater than that of KDP. The mechanical strength of the crystal is determined by Vicker’s Hardness test.
