Vickers microhardness study was carried out on the (110) face of the gel-grown cadmium mercury thiocyanate (CMTC) single crystal, subjected to the loads 10, 25 and 50 g. The measurements were made at room temperature with the indentation time as 10 s. Vickers hardness number Hv was calculated and it is found to increase with the applied load. Mayer's index number 'n' and elastic stiffness constant were calculated. The anisotropy of the crystal is also studied. The results are discussed in detail. © 2007 Elsevier B.V. All rights reserved.

Vickers microhardness studies on cadmium mercury thiocyanate (CMTC) single crystals grown in silica gel

Some bimetallic thiocyanate complexes exhibit excellent nonlinear optical properties. Single crystals of one such material, zinc mercury thiocyanate ZnHg(SCN)4 have been grown in silica gel with gel technique by the process of diffusions and the optimum growth condition has been studied. Crystals of 4 mm length have been obtained. Their structural, optical and thermal properties have been studied. Structural analysis was carried out using an X-ray diffractometer and the crystal structure was confirmed to be tetragonal. Fourier transform infrared spectrum was obtained to confirm the functional groups. Transmission spectrum has been recorded in the solution state and the cut-off wavelength has been determined. Thermal stability of the grown crystal has been investigated by thermogravimetric and differential thermal analyses. Nonlinear optical property of the crystal has been confirmed using the Kurtz powder technique and a study of its second harmonic generation efficiency in comparison with urea has been made. © 2007 Elsevier Ltd.

Study of optimum growth condition and characterization of zinc mercury thiocyanate (ZMTC) single crystals in silica gel

Some bimetallic thiocyanate complexes exhibit excellent nonlinear optical properties. Single crystals of one such material Zinc Cadmium Thiocyanate ZnCd(SCN)4 abbreviated as ZCTC have been grown in Silica gel using gel technique by the process of diffusion. Colorless transparent crystals of size 12 mm × 2 mm × 1.3 mm have been obtained. Structural analysis has been carried out in powder form and for single crystal using X-ray diffractometer. Single crystal X-ray diffraction analysis reveals that the crystal lattice of ZCTC is tetragonal. From powder X-ray diffraction analysis the diffraction planes have been identified and unit cell parameters are determined. © 2007 Elsevier B.V. All rights reserved.
