Single crystal of an organic nonlinear optical (NLO) material, 2,4-Dnitrophenylhydrazine (DNPH), was grown by slow cooling method. Powder X-ray diffraction (PXRD), Fourier transform infrared (FT-IR) FT-Raman and NMR studies have confirmed respectively the crystal structure and functional groups of the grown crystal. Crystalline perfection of single crystals was evaluated by high resolution X-ray diffractometry (HRXRD) using a multicrystal X–ray diffractometer and found that the grown crystals are nearly perfect. UV-Visible-NIR spectral analysis was used to determine the optical constants and band gap of DNPH. Fluorescence spectrum of DNPH was recorded.
