Abstract

Abstract: We reported the bulk size with a dimension of 18×5×5 mm 3 single-crystals of 18C6(Ba)(SCN)2 .H2 O [18-crown-6-ether barium(II) bisthiocyanate monohydrate]; abbreviated as BCBT, have been grown from an aqueous solution via slow evaporation solvent technique(SEST). The grown pristine single-crystals have characterized by single crystal X-ray diffraction (XRD), FT-IR, micro-Raman, and UV-Vis-NIR spectral studies. BCBT crystallizes in a monoclinic with a non-centrosymeetric space group of P21 crystal system. Additionally, the chemical etching studies showed that the reverse crystal growth rates of BCBT. The FT-IR studies confirmed the present of functional groups in the grown single-crystal of BCBT. Interestingly, the CN stretching observed at 2012 cm −1 is clearly shown the N-bonded nature of SCN with Ba 2+ . Moreover, the micro-Raman spectrum is used to further additional confirmation of BCBT single-crystal. In the entire visible region, the BCBT crystal has found to be wide (UV-Vis-IR) optically absorption from 231 to 800 nm, which is suitable for optoelectronic applications. The laser damage threshold measurements on the BCBT crystal with Q-switched Nd: YAG laser of fundamental wavelength 1064 nm (QUANTA RAY Model LAB – 170 - 10, pulse width 10 ns and repetition rate 6 Hz used as the source of light for laser damage threshold experiment. Moreover, the thermal stability of grown BCBT is stable up to 289 °C. From the results reveal that the sample possess admirable thermal stability compared to other IOPS series such as CLTC (171°C), and ACCTC (241°C).
