Abstract

Potassium Hydrogen Phthalate crystal doped with amino acids L-Phenylalanine and L-Tryptophan (0.05mol %) were grown by slow evaporation solution growth technique. Structural difference between undoped and doped crystal has been studied by XRD method. Functional groups were identified by FTIR spectroscopy. The TG-DTA results establish the good thermal stability of the material. Mechanical strength of the grown crystal was estimated by Vicker’s hardness test. The dielectric constant and dielectric loss has been studied as a function of frequency of the doped KHP crystals. 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.
