|Abstract:||The zirconium triselenide (ZrSe₃) single crystal has been grown by chemical vapour transport technique using iodine as a transporting agent. The optimum condition for the growth of this crystal is given. The stoichiometry of the grown crystals was confirmed on the basis of energy disperse analysis by X-ray (EDAX) and remaining structural characterization was accomplished by X- ray diffraction (XRD) studies. The lattice parameters obtained from the XRD analysis were a= 5.45 Å, b=3.74 Å and c=9.44 Å. This crystal is found to possess monoclinic, layered structure. The X-ray density was found to be 5.63 g/cc and volume was calculated about 193.50 Å³. The optical band gap of the as-grown crystal has been carried out with the help of optical absorption spectra in the range 700 - 1400 nm.|
