The novel organic single crystal 2-amino-5-chloropyridinium-trifluoroacetate (2A5CTFA) has been synthesized and grown successfully using methanol as solvent by continuous slow evaporation technique. The X-ray diffraction results reveals that the crystal 2-amino-5-chloropyridinium-trifluoroacetate crystallizes into monoclinic crystal system with the noncentrosymmetric space group Pc. The vibrational spectrum of the sample by FTIR and FT-RAMAN study confirms the characteristic functional groups of the 2A5CTFA crystal. The optical absorption spectrum shows 85% of transmittance in the entire UV-Vis-NIR region with cut-off wavelength at 345 nm. The crystal has a thermal stability of 137° C without any major weight loss in the TG curve. The photoluminescence spectrum of the crystal has a prominent violet emission peak centered at 388 nm. The dielectric behavior of the crystal measured with various frequencies at different temperatures reveals the normal behavior for optical materials. The second order NLO effect from the crystal is confirmed by the emission of green signal from the crystal upon tested with the aid of Kurtz powder analysis using Nd:YAG laser. The laser induced surface damage threshold value of the crystal is found to be 1.05 GW/cm2. Overall, the outlined properties of the grown crystal makes it suitable for opto-electronic and nonlinear optical device applications. |
