AbstractHexamethylenetetramine succinate was synthesized and good quality single crystals with the size of 14 mm × 6 mm × 4 mm were grown by the slow evaporation solution growth technique at room temperature. The single crystal XRD revealed that the grown crystal belongs to the monoclinic system with the space group of P21/c. The presence of functional groups in the crystal was identified using FT-IR technique. The optical behavior was examined through UV-Vis-NIR studies. The photoconductivity study exhibited the positive photoconductivity nature of the grown crystal. Microhardness studies revealed the soft nature of the crystal. The nonlinear refractive index (n2), nonlinear absorption coefficient (β) and third order nonlinear optical susceptibility χ(3) of the crystals were measured by Z-scan studies.

AbstractNew organic single crystals of 2-amino-6-methylpyridinium 2-hydroxybenzoate (2A6M2H) were grown by slow evaporation solution growth technique at room temperature. The grown crystal structure was studied using single crystal XRD. Crystalline nature and phases were confirmed by powder XRD analysis. FT-IR study was used to identify the functional groups present in the compound. UV-Vis study revealed that the lower cut off wavelength of the crystal is at 350 nm. The dielectric studies indicated the low value of dielectric loss at high frequency. Mechanical properties of the crystals were studied using Vickers microhardness test. The Z-Scan studies were conducted for the crystal using He–Ne laser.

Newly identified organic single crystals of 8-hydroyquinolinium 2-chloro 4-nitrobenzoate (HQ2ClNB) were grown by the slow evaporation solution growth technique (SEST) using methanol as a solvent. It crystallizes in monoclinic crystal system with a space group of P21/c. Crystalline nature and phases were confirmed by powder X-ray diffraction (XRD). The existence of various functional groups in the molecule was identified using the Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) technique. Optical transmission window and lower cut-off wavelength of the HQ2ClNB crystal have been evaluated by UV–Visible–NIR studies. Dielectric and photoconductivity studies were recorded. Third-order nonlinear optical susceptibility [Formula: see text] of the crystals were evaluated by [Formula: see text]-scan studies.

L-Valine zinc acetate (LVZA) was synthesized and its solubility was estimated in the solvent of double distilled water. Single crystals of LVZA were grown by slow evaporation solution growth technique. The cell parameters were obtained by single crystal X-ray diffraction study. Functional groups of LVZA were identified by FTIR analysis. UV-vis-NIR spectral studies showed the optical nature of LVZA. Kurtz powder technique revealed the SHG efficiency of LVZA. Thermal properties of the grown LVZA crystal were studied from TGA/ DTA and DSC spectrum. Vickers’s mechanical hardness values were found for the grown crystal.

Solution Growth Technique

The stable long time growth with the use of Si -C-Ti ternary solution was realized　by improving the thermal condition during the growth. We have succeeded in obtaining a maximum 10 mm thick bulk 6H-SiC crystal, which is the largest bulk crystal ever obtained by the solution growth technique. The obtained crystal was free of cracks and exhibited a homogeneous light green color. The crystallinity of the grown crystal was characterized by X-ray rocking curve measurements using (0006) reflection and by the molten KOH etching. The mapping of the full width at half maximum (FWHM) revealed the average FWHM around 30 arc seconds and the minimal FWHM under 16 arc seconds. The etch pit density (EPD) was typically in the range between 104 and 105 cm-2, which was comparable to that of the crystal seed.
