Growth And Characterization Of Strontium Chloride Doped Sodium Penta Fluoro Antimonate Single Crystals

Abstract

The slow evaporation method has been used to grow strontium doped sodium penta fluoro antimonate crystals, an inorganic optical material. The grown strontium doped sodium penta fluoro antimonate crystal by single X-ray diffraction (XRD) analysis it is its find that the title compond belong to the orthorhombic system with the non-centro symmetric space group P2₁2₁2₁. The functional groups present  the grown  crystal are examined using the FTIR spectrum. UV-Vis experiments determine the band gap is measured 5.4 eV. TG/DTA investigations have been estimated the melting point of Strontium Chloride doped Sodium Penta Fluoro Antimonate is 324.6⁰C .Using dielectric studies activation energy at 1kHz is determine as 0.00274 eV. The grown Strontium Chloride doped Sodium Penta Fluoro Antimonate single crystal's elemental composition is determined by energy dispersive X-ray analysis (EDAX). At room temperature, impedance spectroscopy measurements were performed on the grown crystal in the range of 100 Hz to 1 MHz. There was just one semi-circle observed in the growing crystal's Nyquist plot. The optical limiting characteristics and nonlinear optical absorption are analyzed using the open-aperture Z-scan approach. The coefficient of nonlinear absorption is 1.5 x10 ^-10 W ̸ m²    and 1.31 x10¹² W ̸ m² is the optical limiting value for threshold.
