Growth and characterization of sulphamic acid single crystals: A nonlinear optical material

The nonlinear optical single crystals of sulphamic acid (SA) were grown by slow evaporation solution growth technique. The grown crystal was confirmed by powder X-ray diffraction. The functional group of the grown crystal was found by FT-IR studies. The thermal and UV–vis transmittance studies were performed to know the thermal and optical behavior, respectively. The NLO property of the crystal was tested by Nd:YAG laser as a source.
