Growth and Characterization of Guanidinium Trifluoroacetate – Second Harmonic Generation from a Centrosymmetric Crystal


Guanidinium trifluoroacetate (GTFA), a semi-organic non-linear optical material with molecular formula C3H6F3N3O2, has been synthesized at ambient temperature. Second harmonic generation (SHG) efficiency has been observed in this crystal though it crystallizes in centrosymmetric space group. Bulk single crystal of GTFA with a size of 22 x 7 x 2mm3 is successfully grown by submerged seed solution method. The grown crystals of GTFA have been subjected to various characterization studies such as X-ray diffraction, CHNS, FTIR analysis, UV-Vis spectrum, TGA/DTA, powder SHG test, laser damage threshold and microhardness studies.
