| Description |
Ammonium malate (AM), an organic nonlinear optical material, has been synthesized and single crystals, with dimensions up to 38 x 35 x 27 mm(3), have been grown from aqueous solution. The crystal structure of AM has been determined, and it belongs to the non-centro symmetric space group Cc. The structural perfection of the grown crystals has been analysed by high-resolution X-ray diffraction (HRXRD) rocking curve measurements. Fourier transform infrared (FTIR) spectroscopic studies were also performed for the identification of different modes present in the compound. The UV-vis transmission spectrum has been recorded in the range 200-1100 nm. The second harmonic conversion efficiency of AM was determined using the Kurtz powder technique; it was observed to be greater than that of KDP. Thermal behaviour of AM was studied by TG and DTA. The dielectric and mechanical behaviour of the specimen was also studied.
