Abstract Synthesis of phase pure Sb2S3 in open atmosphere has been a long-time challenging task due to the oxidation of metal. Here, we demonstrate a robust, one-step solution approach for synthesis of Sb2S3 thin films in open air atmosphere. One-step thermolysis of Sb-MPA complex obtained by mixing antimony chloride and 3-Mercaptopropionic acid (3-MPA) in polar and non-polar solvents yields phase pure thin films. Upon changing the concentration of sulphur in the solvent and polarity of solvent, different microstructures of Sb2S3 such as nanostripes, nanorods and tubular morphology evolve. Irrespective of sulphur concentration in the precursor solution, Sb2S3 thin films are always phase pure and formed in stoichiometric composition. The films are photoconductive in nature and morphology of Sb2S3 influences the photoconductivity. This novel and facile methodology will open new avenues for direct deposition of Sb2S3 thin films for wide range of applications including optoelectronics, photovoltaics and photocatalysis research.

Sb-巯基丙酸配合物在环境空气中一步热解，用于生长具有可控微结构的 Sb2S3 薄膜

摘要 由于金属的氧化，在开放大气中合成纯相 Sb2S3 一直是一项具有挑战性的任务。在这里，我们展示了一种在露天环境中合成 Sb2S3 薄膜的稳健的一步解决方法。通过在极性和非极性溶剂中混合氯化锑和 3-巯基丙酸 (3-MPA) 获得的 Sb-MPA 复合物的一步热解产生纯相薄膜。随着溶剂中硫的浓度和溶剂极性的改变，Sb2S3 的不同微观结构如纳米条、纳米棒和管状形态发生变化。无论前体溶液中的硫浓度如何，Sb2S3 薄膜总是相纯的，并以化学计量组成形成。这些薄膜本质上是光电导的，Sb2S3 的形态会影响光电导率。
