Crystal growth, Spectral, Thermal and Optical properties of Phthalic Anhydride (PA) single crystal

Abstract

Organic single crystal of Phthalic Anhydride (PA) was successfully grown by slow evaporation method. The structure of the grown crystal was confirmed by X-ray diffraction analysis. FT-IR. and FT-Raman spectral analysis of the crystalline sample reveal that it consists of all functional groups. The number of protons was identified from H-1-NMR spectral analysis. UV-visible and photoluminescence spectral analyses were carried out for the grown crystals. The thermal behavior was studied with TGA-DTA analyses. The existence of second harmonic generation (SHG) signal was observed using Nd:YAG laser with a fundamental wavelength of 1064 nm.
