Revealing the formation mechanism and band gap tuning of Sb₂S₃ nanoparticles.

ABSTRACT: Sb₂S₃ is a promising nanomaterial for application in solar cells and in the fields of electronics and optoelectronics. Herein, Sb₂S₃ nanoparticles were prepared via the hot-injection approach. In contrast to earlier work, the reaction temperature was decreased to 150 °C so that the reaction was slowed down and could be stopped at defined reaction stages. Thereby, the formation mechanism of the nanomaterial and the associated kinetics could be revealed. Based on morphological and structural analyses, it is suggested that seed particles (type 0) formed immediately after injecting the antimony precursor into the sulfur precursor. These seeds fused to form amorphous nanoparticles (type I) that contained a lower percentage of sulfur than that correspo
