Growth and characterization of pure and doped bis(thiourea) cadmium acetate single crystals

Single crystals of pure and Zn2+ doped bis(thiourea) cadmium acetate (BTCA) were grown by slow solvent evaporation technique. The grown crystals were confirmed by single crystal XRD. The metal coordination with thiourea through sulphur in both pure and doped BTCA was ascertained by FTIR studies. The optical transmission spectra of pure and doped BTCA crystals were recorded and the results are discussed. The thermal decomposition of pure and doped BTCA crystals was investigated by means of thermogravimetric analysis (TGA). The dielectric response and photoconducting nature of the crystals were also investigated and reported.
