Growth And Studies Of Nickel Chloride Doped Sodium Fluoro Antimonate Crystals

R.Kumuthini, P.Selvarajan, S.Selvaraj

Undoped and Nickel chloride doped sodium fluoro antimonite (SFA) crystals were grown by slow evaporation technique at room temperature. The solubility of the samples in water has been measured at different temperatures. The values of lattice  parameters of the samples were obtained by X-ray diffraction (XRD) studies. The microhardness was measured for the samples at different applied loads. EDAX spectrum has been recorded for nickel chloride doped SFA crystal to identify the elements presents in the sample. The decomposition point of the sample was identified by TG/DTA studies. Laser damage threshold (LDT) value of the samples was measured and dielectric properties were measured at different frequencies and temperatures. Second harmonic generation (SHG) efficiency of the samples was measured using Kurtz powder technique.
