| A semi organic L-histidinium ammonium acetate (L-HAA) single crystal has been grown by slow evaporation technique. Single crystal X-ray diffraction studies confirm the monoclinic crystal system. Vibrational spectroscopic studies confirm the various functional groups present in the crystal. The ultraviolet-visible spectrum analysis has been carried out and the optical band energy gap for a grown crystal is calculated to be 5.5 eV which indicates that the material is a good insulator and provides large transmission in visible region. Thermogravimetric-differential thermal analysis reveals that the material is thermally stable up to 273.02°. The second harmonic generation efficiency of L-HAA crystal is found to be 0.68 times lesser than that of KDP. |
