The process and various performance tests of producing single crystal of mercury cadmium bromide thiocyanate (MCBT) using a mixed solvent of ethanol and deionized water are described in the text. The crystal shows excellent performance in second-harmonic generation proficiency, UV cut-off wavelength, thermal stability, mechanical limits, and third-order nonlinear optical performance.
Single crystal of mercury cadmium bromide thiocyanate (MCBT) has been produced by a slow cooling technique with a mixed solvent of ethanol and deionized water (1:1). The lattice constant of the MCBT crystal evaluated by single-crystal X-ray diffraction analysis illustrates that the titular crystal belongs to orthorhombic system. The second-harmonic generation proficiency of MCBT is 5.64, more prominent than KDP crystal. The transmission spectrum gives UV cut-off wavelength of 328 nm. The thermal stability of 201 degrees C was validated by thermogravimetric and differential thermal analyses. The mechanical limits of MCBT crystal were evaluated by the microhardness test. The dielectric study was carried out with varying frequency at different temperatures. The feature of surface was examined by scanning electron microscope for the titular crystal. Third-order nonlinear optical performance was determined by Z-scan technique.
