Nitrates/Sulphides

Antimony sulfide (Sb2S3) is a kind of semiconductor with its interesting high photosensitivity and high thermoelectric power. Antimony sulfide is a layer-structured direct bandgap semiconductor with orthorhombic crystal structur. Sb2S3 is considered as a promising material for solar energy due to its band gap which covers the range of the solar spectrum.

Sb2S3 has been extensively investigated for its special applications as a target material for microwave devices, television cameras and switching devices, rechargeable storage cell , and various optoelectronic devices .

Antimony sulfide (Sb2S3) fulfils the optical requirements to obtain an electronic bandgap in the visible or the near-infrared (NIR) region, depending on its amorphous or crystalline nature. The electronic gap of Sb2S3 lies around 2.2 eV (564 nm) for amorphous and 1.78 eV (697 nm) for crystalline Sb2S3 thin films. Sb2S3 nanomaterials have been synthesized by different methods, such as solvothermal reaction, hydrothermal treatment, refluxing polyol process, sonochemical method, chemical vapor transport reaction, etc.

 Sb₂S₃ is a multifunction material that could be used as an absorber or a sensitizer for photovoltaic device, photochemical catalysis, and photodetector. Besides, Sb and S are comparatively abundant, low-cost, and low-toxicity elements, making it potential for large-scale application. Antimony sulfide has a unique processibility. They can be vacuum-evaporated at a low temperature (~ 400 °C) or solution-processed using various materials.
