Abstract
Single crystals of Tri glycine phosphoric acid (TGPA) a semi organic non-linear optical material, has been grown from solution by slow evaporation method at room temperature. The title compound was synthesized and purified by repeated recrystallization process. The growth of crystals was confirmed at pH 2.8. The crystals were characterized by single crystal X-ray diffraction and Fourier transform Infrared Spectroscopic (FTIR) analysis. The formation of TGPA crystal was confirmed by powder XRD analysis. The range and percentage of optical transmission was ascertained by recording UV-vis-NIR spectrum. The second harmonic generation behaviour of TGPA crystal was tested by Kurtz-Perry powder technique and its mechanical hardness was estimated by Vickers microhardness method.
