Thermal and nonlinear optical properties of semiorganic single crystal: L-Threonine p-nitrophenolate (LTPNP)

Abstract

The single crystal of L-Threonine 4-nitrophenolate developed by uncomplicated solution growth process. The grown crystal is analysed by using various characterization techniques. The structural analyses have been carried out by using Powder XRD method. Fourier Transform Infrared and Nuclear Magnetic Resonance spectra analysis confirms the functional groups exist in grown crystal. The thermal steadiness of L-Threonine 4-nitrophenolate crystals analysed by Thermo-gravimetric (TG) and Differential Thermal analyses (DTA). The sharp diffraction peaks in XRD pattern confirms the well crystalline nature of the synthesized sample. TG and DTA analysis prove that the synthesized sample possess good thermal constancy up to150°C. The UV-visible absorption studies show that the crystal is clearly visible in the whole visible region of the spectrum. Kurtz -Perry powder technique and Z-scan technique reveals the excellence of the synthesized samples for non linear optical (NLO) uses.
