The Lanthanum doped Sulphamic Acid (SA) single crystal was grown by slow evaporation solution growth technique. The Presence of Lanthanum was confirmed by EDAX. The unit cell parameters of the grown crystal were confirmed by single crystal X-ray diffraction. The functional groups of the grown crystal were found by FT-IR study. Thermal and UV-vis absorption studies were performed to know the thermal and optical behaviours of the grown crystal respectively.Keywords

Thiourea doped Sulphamic acid (Th : SA) single crystals were grown successfully by slow-evaporation technique. To identify the morphology and structure, the as grown crystals were subjected to characterization like powder and single XRD analysis. UVVis-NIR spectrum and FTIR studies are performed to identify the cut-off wavelength and the various functional groups present in the grown crystal. Second harmonic generation were investigated to study the linear and nonlinear optical properties. In order to ascertain the thermal stability of the crystal, thermo-gravimetric analysis (TGA), differential thermo-gravimetric analysis (DTA) and differential scanning calorimetry (DSC) were also carried out.Keywords

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

Every material has a unique set of electrical characteristics that are dependent on its dielectric or insulation properties. In the present work, Lanthanum and Cerium doped sulphamic acid single crystals (La : SA) and (Ce : SA) were grown by slow solvent evaporation technique at room temperature and their dielectric properties are studied. The variation of dielectric constants, dielectric loss and conductivity at different temperatures and frequencies in the applied field are measured and their electrical behaviors are analyzed.Keywords
