Abstract
Antimony sulphide (Sb2S3) nanorods were prepared by the thermolysis of antimony(III) tris(N-ethyl-N-phenyl dithiocarbamate) complex in hexadecylamine, and were studied for different structural parameters. X-ray peak broadening analysis by Williamson-Hall and size-strain analyses were used to estimate the crystallite size and strain, including other physical parameters, such as Young's modulus, stress, and energy density. The models indicated that the nanorods experienced lattice contraction occasioned by the synthetic route. Different values of crystallite size were obtained for the explored models, which may be due to their anisotropic nature. Calculated lattice strain and crystallite size obtained from the Williamson-Hall methods were - 5.5 x 10(-4) and 72.6 nm; - 2.5 x 10(-4) and 103.4 nm and - 6.6 x 10(-4) and 90.5 nm from the uniform deformation model (UDM), uniform stress energy density model (USDM), and uniform deformation energy density model (UDEDM), respectively. The lattice strain and energy density obtained from the UDEDM model were 2.0 MPa and 6 kJ/m(3). Crystallite sizes of 85.1 and 62.5 nm and strains of - 3.49 and - 1.6 were obtained from the size-strain plot and Halder Wagner methods. While the Scherrer plot and the uniform deformation stress models gave comparable crystallite size values, other models gave lower values.
