Growth and characterization of triglycine calcium dibromide, a semiorganic NLO material

Single crystal X-ray diffraction analysis was used to estimate the cell parameters of the grown crystals. The structural perfection of crystals has been analyzed by high-resolution X-ray diffraction (HRXRD) rocking curve measurements. Energy dispersive X-ray analysis confirms the presence of elements in the title compound. The grown crystals were tested by FTIR, thermogravimetric and differential thermal analysis, UV-vis-NIR analysis, and dielectrical and mechanical studies. The transmittance of TGCB crystal has been used to calculate the refractive index n, the extinction coefficient K and both the real εr and imaginary εi components of the dielectric constant as functions of wavelength. The second harmonic conversion efficiency of TGCB was determined using the Kurtz and Perry powder technique; it was observed to be greater than that of KDP.
