Growth, Structural, Optical, Thermal and Mechanical Studies of a Novel Nickel Sulphate Doped Sulphamic Acid Single Crystals for Optical Applications
A novel good quality crystal of nickel sulphate doped sulphamic acid (NSSA) has been grown by slow evaporation solution growth technique at room temperature. The single crystal XRD confirm that the grown single crystal belongs to the monoclinic system with the space group of P2_1/C. Powder XRD studies show good crystallinity of the grown sample. UV-VIS studies reveal that the grown crystals have the good optical transmission in the whole visible region. Photoluminescence spectra for the NSSA crystals were recorded using fluorescent spectrophotometer in the range from 200 nm to 900 nm. EDAX analysis declare that (Ni) ion is incorporated in the compound. The Surface analysis is carried out using a scanning electron microscope (SEM) which show that the atomic layers have different sizes and portray. The surface has fine morphology with microcrystal and mild cracks. Thermo-gravimetric analysis measure the dehydration temperature of the nickel sulphate doped sulphamic acid crystal is about 130°C. Vickers hardness analysis validate that these crystals has good mechanical strength. The non linear optical property of the sample was examined by NLO studies.
