Abstract: Potassium Hydrogen Phthalate (KHP) crystals doped with Amino acid L-Asparagine (0.1 & 0.15mol %) were grown by slow evaporation technique. Structural characterizations of the grown crystals were carried out by powder X-ray diffraction method. It reveals that the grown crystals of undoped and doped KHP crystals are in orthorhombic structure. The functional groups were identified by Fourier Transform Infrared Spectroscopy. The enhancement of optical transparency in the doped KHP crystal was recorded using UV-Visible spectrophotometer. Mechanical strength of the grown crystal was estimated by Vickers hardness test. The TG-DTA results establish the good thermal stability of the material. The second harmonic generation has been confirmed by the Kurtz powder method. It was observed to be greater than that of KDP. The photoluminescence study also observed.
