Author(s): R Ashwini, Dr. D Mohan Radheep
Abstract: Now-a-days technology is fully occupied by the semiconductor materials, piezoelectric, ferroelectrics, sensitive crystals and crystalline films. The significance of crystal growth both in theoretical and experimental aspects can be realized by developing such above cited single crystal materials. The preparation of single crystal is mainly based on the availability and nature of the starting materials and their physical-chemical properties. The present photonic technology mainly depends on the organic non-linear optical (NLO) materials. The idea of combining the in-organic molecules with the organic molecules results in production of new non-linear crystals. These crystals are ideally had large non-linearity of conjugated organics and favorable crystal growth characteristics and mechanical properties of ionic salts. In the present investigation, large size crystal of L-Histidine sodium nitrate has been successfully grown by slow evaporation technique. The grown crystals were colourless and transparent. The grown crystals were characterized by single crystal and powder X-ray diffraction to find the structure of crystals. The FT-IR analysis was made to identify the functional groups. The UV/Visible absorption studies were carried out to determine the optical transparency of the crystals. The dielectric and SHG studies have been carried out. The mechanical behavior of the grown crystal was analysed by micro hardness test.
