An inorganic material Sodium PentaFluoroAntimonate (Na2SbF5) single crystal, have been grown by slow evaporation growth technique.Single crystal X-ray diffraction (XRD)andpowder X-ray diffractionstudies shows that the grown crystal belongs to the orthorhombic system with the non-centrosymmetric space group P212121. The FTIR spectrum is used to analyze the functional groups present in the grown crystal. Energy dispersive X-ray analysis (EDAX) is used to find the elemental composition of the grown Sodium PentaFluoroAntimonate single crystal.The optical properties of the grown crystal were analyzed by UV-Vis studies. The photoluminescence property of the grown crystal has been analyzed. The thermal properties of the grown crystal have been studied by using TG/DTA studies. The dielectric studies were analyzed by using the parallel plate capacitor method. The Mechanical property of grown crystals studied using microhardness studies.The impedance spectroscopic studies were carried out on the grown crystal from 100 Hz to1 MHz range at room temperature. The Nyquist plot of the grown crystal exhibited the presence of one semi-circle.We can also analyzed by effective separation efficiency of photo induced electron hole pairs and a faster interfacial charge transfer.The nonlinear optical properties of the grown Sodium PentaFluoroAntimonatecrystal were measured using the Z-scan technique. The grown Sodium PentaFluoroAntimonatesingle crystals optical limiting threshold values were analyzed.
