Abstract

Antimony sulphide (Sb2S3) is an interesting material for numerous optoelectronic applications due to its unique structural, morphological and optical properties, which are highly tuneable by different process parameters. By using a heat-up approach, antimony(III) tris(N-ethyl-N-phenyldithiocarbamate) has been utilised as single source precursor to prepare Sb2S3 in oleylamine (OLA). The effect of the reaction time on the structural, morphological and optical properties of the as-synthesized Sb2S3 was evaluated. The structural properties were explored using the Rietveld analysis to model the crystal structure of the antimony sulphide produced, and Willamson-Hall analysis was used to study the strain in the prepared materials. A good control of shape, with uniform nanorods, were obtained without any secondary morphology throughout the reaction time considered, with aspect ratio that varied from 6.1 to 10.7. The band gap energies estimated from the absorption spectra of the nanomds were in the range of 1.5-1.7 eV.
