Abstract
Growing crystals increases, day by day due to their remarkable applications. In the present work we are interested in investigating the effect of the dopant in the crystal structure and general characterization of pure Sulphamic Acid (SA) single crystal. Hence, neodymium doped Sulphamic Acid (Nd:SA) single crystal was grown by low temperature solution growth method. The presence of neodymium in the grown crystal was confirmed by EDAX spectrum. The cell parameters of the grown crystal were determined by single crystal X-ray diffraction. The functional groups of the grown crystal were anlysed by FT-IR study. Thermal and UV-vis-NIR transmission studies were performed to know the thermal and optical behaviours of the grown crystal. The non linear optical behavior was confirmed by Kurtz – Perry powder technique. Keywords: Growth from Solution, X-ray Diffraction, FTIR, Optical Studies, Powder X-ray Diffraction, EDAX

Summary
Sulphamic Acid (SA), H2NSO3H is an important industrial chemical compound, which is strongly soluble in water. The growth of the single crystal plays an important role in both science and in technological applications, such as photonics, optoelectronics, optical communication, optical image processing etc[2]. The search of new organic, inorganic and semi organic non linear optical materials which have been increased in recent times. We are interested to do a systematic study on the effect of a rare earth, such as neodymium on pure SA. This work is based on the systematic studies on the effect of neodymium on sulphamic acid single crystals. The crystalline perfection, structure, incorporation of dopants, presence of funtional groups, thermal, optical, and non linear optical behaviours in (Nd:SA) were revealed by X-ray diffraction, EDAX, FTIR, UV-vis-NIR, TG-DTA studies and kurtz perry technique respectively
