Simple Synthesis of Antimony Sulfide Nanstructures Via a One-Step Method

As an excellent semiconductor, Sb2S3 exhibits importantapplications in photovoltaic [1], photosensors [2], solarenergy, and photoelectronics [3, 4], optical nanodevicesoperating in the near-infrared [5]. So far, variousmorphologies and architectures of Sb2S3 nanostructureshave been reported, such as hollow cones, nanotubes, rodlikedendrites, and straw-tied-like. Many efficienttechniques were developed to prepare nano and bulkSb2S3, mainly including chemical vapor deposition,sonochemical, ambient-temperature, hydrothermal, andsolvothermal, and thermal decomposition methods.Herein, we present a hydrothermal method which the trickin hydrothermal synthesis of Sb2S3 nanostructurespresented here is the using of thioglycolic acid (TGA) as asulfur source and stability agent which was previouslyused as the stability agent to prevent the chalcogenidenanocrystals from aggregating [6, 7].
