Abstract

Organic single crystal of Guanidine Acrylate (GuAcr) was grown by simple inexpensive slow evaporation technique. The grown crystal was subjected into various characterizations like single crystal XRD, UV-Vis, FTIR studies, electrical, mechanical properties and SHG technique. The XRD data shows that the crystal belongs to orthorhombic structure. The UV-Vis spectral studies observed that the cutoff wavelength of the grown crystal is 320nm. Optical band gap of the grown crystal was also calculated, and it was found to be 3.99 eV. Vibrational frequencies of GuAcr crystal were confirmed by FTIR spectra. Electrical properties of the GuAcr single crystals were studied using impedance spectroscopy. Decreasing impedance with increasing temperature is indicated that the negative temperature co-efficient of resistance behavior like an insulator. Dielectric response of the crystal with varying frequencies was also studied. Second harmonic generation of the title compound was studied using Kurtz Perry- powder SHG technique. It reveals that as grown crystal is suitable for Nonlinear Optical (NLO) device fabrications.
