Abstract
Single crystals of sodium chloride doped Potassium Hydrogen Phthalate (KHP) were grown from aqueous solution by slow evaporation method at room temperature. The powder X-ray diffraction analysis was carried out and lattice cell parameters estimated. FTIR studies confirm the presence of functional groups and slight distortion of groups due to doping of sodium metal. UV-visible and photoluminescence spectral studies revealed to understand the optical properties. The NLO property of grown crystals has been confirmed by Kurtz powder technique. Dielectric studies of samples showed that dielectric constant decreased slowly with increasing frequency and attains saturation at higher frequencies.

Summary
Second order nonlinear optical (NLO) materials have recently attracted much attention due to their potential applications in emerging optoelectronic technologies [1]. Materials with large optical nonlinearities with stable physical and thermal efficiencies required for many of these applications. (2015) Effect of NaCl Doping on Growth, Characterization, Optical and Dielectric Properties of Potassium Hydrogen Phthalate (KHP) Crystals. Potassium hydrogen phthalate (KHP) crystal, with chemical formula K (C6H4COOH·COO), is well known material for its application in the production of crystal analyzers for long-wave X-ray spectrometers [4]-[7]. KHP crystallizes in orthorhombic structure with space group Pca21 [10] [11] It has platelet morphology with cleavage along (010) plane.
