摘要: A new organic nonlinear optical material semicarbazone of p-hydroxy acetophenone (SPHA) was synthesized. Good quality single crystal of SPHA was successfully grown by slow evaporation method at room temperature. The crystal system was identified and lattice dimensions were measured from the single crystal X-ray diffraction (XRD) analysis. The various planes of reflection were identified from the powder XRD pattern. The presence of functional groups was qualitatively found by Fourier transform infrared (FTIR) spectral analysis. The proton and carbon nuclear magnetic resonance ((HNMR)-H-1 and (CNMR)-C-13) spectral studies confirmed the presence of hydrogen and carbon bonded network in the grown crystal. The UV-Visible absorption spectrum was recorded to study the optical transmittance in the range from 200 to 800 nm. The thermal stability of compound was determined by thermogravimetric and differential thermal analysis (TG-DTA) traces. The existence of second harmonic generation (SHG) signal was observed using Nd:YAG laser with fundamental wavelength of 1064 nm.
