Growth and Characterization of Unidirectional Grown Imidazolium L-Tartrate (IMLT) Single Crystal by SR Method

The second order non-linear optical material Imidazolium L-Tartrate (IMLT) seed crystal was successfully grown by slow evaporation method. <0 0 1> plane unidirectional crystal was successfully grown by Sankaranarayanan and Ramasamy (SR) method. The growth of conventional and SR grown crystals were optimized. Cell parameter, space group and morphology of the grown conventional method crystal were found by single XRD. Transparency of the grown IMLT crystals by conventional and SR method were compared by UV-Vis-NIR spectroscopy. Emission spectrum of the grown IMLT crystals were analysed by Photoluminescence. Dielectric constant and Dielectric loss of the grown crystals were analysed. Mechanical strength of the grown IMLT crystals was determined by Vickers hardness test.
