Colloidal spherical stibnite particles high-temperature metallo-organic synthesis.

Antimony trisulfide (SbS) is an emerging semiconductor with a high absorption coefficient and a bandgap in the visible range. This makes it a promising material for various electronic and optoelectronic applications. However, one of the main challenges is still the synthesis of the material, as it is usually obtained either as a nanomaterial in its amorphous form with inferior optical properties or in crystalline rod-like structures in the micrometer or sub-micrometer range, which leads to application-related difficulties such as clogging in inkjet printing or spraying processes or highly porous layers in film applications.

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

SbS is a promising nanomaterial for application in solar cells and in the fields of electronics and optoelectronics. Herein, SbS 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.
