Antimony sulfide has a unique processibility.

Besides, Sb and S are comparatively abundant, low-cost, and low-toxicity elements, making it potential for large-scale application. Naturally, Sb 2S 3 is a multifunction material that could be used as an absorber or a sensitizer for photovoltaic device, photochemical catalysis, and photodetector. Curiously, the band gap is tunable at the range of 1.1–1.8 eV when sulfur is partly replaced by selenium.

It has a moderate band gap approximately 1.7–1.8 eV in crystalline form (stibnite). Sb 2S 3 has been known as the commonest antimony sulfide, which is a promising semiconductor material for photoelectric semiconductor manufacturing. Besides, a range of semiconductor QDs, such as CdS, CdSe, ZnS, ZnSe, HgTe, CuInSe 2, CuInS 2, and CdHgTe, and base device have been reported everywhere. Typically, lead compound QDs such as PbS and lead halide perovskites have recently emerged as promising candidate materials in photoelectric applications such as photovoltaics, OLEDs, lasing, and photodetectors due to their simple synthesis and satisfactory performance. Quantum dots (QDs) have received a great deal of attention over the past decade owing to their manipulated photoelectric properties and superior solution processibility for device engineering. The E g of Sb 2S 3 QD thin film has been found to be tunable from 1.82 to 1.09 eV via annealing or selenylation, demonstrating the good prospects in photovoltaic application. Their band gaps ( E gs) were calculated according to transmittance spectra. Sb 2S 3 QD thin films were prepared by self-assembly growth and then annealed in argon or selenium vapor. An intensive PL emission at 880 nm was found, indicating Sb 2S 3 QDs have good prospects in near-infrared LED and near-infrared laser application. Photoelectric properties including absorbing and emission were characterized by UV-Vis-IR spectrophotometer and photoluminescence (PL) spectroscopic technique. To fill this vacancy, water-soluble Sb 2S 3 QDs were prepared by hot injection using hexadecyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) mixture as anionic-cationic surfactant, alkanol amide (DEA) as stabilizer, and ethylenediaminetetraacetic acid (EDTA) as dispersant. However, there was lack of information about Sb 2S 3 quantum dots (QDs) because of the synthesis difficulties.
Antimony sulfide skin#
Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed.Antimony sulfide (Sb 2S 3) has been applied in photoelectric devices for a long time. For minor skin contact, avoid spreading material on unaffected skin. Otherwise, continue rinsing until medical treatment is available. In case of skin contact with Hydrofluoric acid ( UN1790), if calcium gluconate gel is available, rinse 5 minutes, then apply gel. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Remove and isolate contaminated clothing and shoes. Administer oxygen if breathing is difficult. Use a pocket mask equipped with a one-way valve or other proper respiratory medical device. Do not perform mouth-to-mouth resuscitation if victim ingested or inhaled the substance wash face and mouth before giving artificial respiration. Give artificial respiration if victim is not breathing. Move victim to fresh air if it can be done safely. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Excerpt from ERG Guide 157 :Ĭall 911 or emergency medical service.
