Potassium dihydrogen phosphate (KDP) is an excellent inorganic nonlinear optical material with different device applications. In the present work, single crystals of pure and p-dinitroaniline doped KDP crystals have been grown from the aqueous solution by slow evaporation technique. The grown crystals have been subjected to various characterizations studies like UV-visible, FTIR spectroscopy, x-ray diffraction, SEM, EDAX and dielectric studies. FTIR spectrum analysis confirmed the presence of p- dinitroaniline in KDP crystals. UV- visible studies suggest that the crystal is suitable for nonlinear applications. Dielectric studies confirmed the single phase and high purity of the crystal.
