Unidirectional growth of Methyl 2-amino-5-bromobenzoate crystal by Sankaranarayanan-Ramasamy method and its characterization

Bulk single crystal of Methyl 2-amino-5-bromobenzoate (M2A5B) nonlinear optical single crystal of size 60 mm length and 15 mm diameter was successfully grown from solution by Unidirectional growth method of Sankaranarayanan-Ramasamy (SR) for the first time in the literature. The growth conditions were optimized and the growth rate of 1.5 mm per day was observed for the SR grown crystal. The crystal system and its lattice parameters were confirmed by single crystal X-ray diffraction studies. The UV-vis transmission, Photoluminescence, Chemical Etching And Mechanical behavior of M2A5B were studied for conventional and SR methods grown crystals and compared. The second harmonic generation efficiency of M2A5B was confirmed by Kurtz-Perry powder method.
