2. METHODS OF CRYSTAL GROWTH TECHNIQUES SLOW EVAPORATION THERMAL VAPORATION CHEMICAL VAPORATION

3. SLOW EVAPORATION TECHNIQUE Under room temperature the solvent is placed for evaporation Glycine and zinc choloride are going to use as dopend Glycine and zinc choloride crystal is obtained

4. PROPERTIES OF GLYCINE Molecular formula : C 2 H 5 NO 2 Molar mass : 75.07 g /mol Appearance : white solid Density : 1.607 g/cm 3 Melting point : 233 °C Solubility : water & ethanol

5. PROPERTIES OF ZINC CHOLRIDE Molecular formula: ZnCl 2 Molar mass :136.315 g/mol Appearance :white crystalline solid hygroscopic Odor: odorless Density: 2.907 g/cm 3 Melting point: 292 °C, 565 K, 558 °F Boiling point :756 °C, 1029 K, 1393 °F Solubility : water, ethanol, glycerol, acetone and alcohol

6. OBJECTIVE To synthesis the Glycine Zinc Chloride (GZC) salt using slow evaporation technique. To grow Glycine Zinc Chloride single crystal. Characterizing the crystals by X-ray Diffraction, FTIR and UV-Vis, Optical and Dielectric studies.

7. NONLINEAR OPTICS Non-Linear optics- ‘ Optics of intense light ’ : We are concerned with the effects that light itself induces as it propagates through the medium. The Study of interaction of light in matter
