摘要

在阳离子表面活性剂肉豆蔻基三甲基溴化铵（MTAB）的存在下，利用两种方法首次获得了硫量子点（SQDs）："自下而上 "和 "自上而下 "两种方法。以硫代硫酸钠为原料，在 MTAB 存在下合成 SQDs，需要在 70 °C 下加热 2 小时，最后得到的溶液具有稳定的光致发光（量子产率为 18%）。以硫为原料的 SQDs 是在过氧化氢腐蚀后加热 12 小时才制成的。实验证明，过氧化氢对硫代硫酸钠合成 SQDs（"自下而上 "技术）是无效的。

Sulfur quantum dots stabilized by myristyl trimethylammonium bromide

For the first time, sulfur quantum dots (SQDs) were obtained in the presence of the cationic surfactant myristyl trimethylammonium bromide (MTAB) using two approaches: “bottom-up” and “top-down”. The synthesis of SQDs from sodium thiosulfate in presence of MTAB required 2 h heating at 70 °C resulting in a solution with stable photoluminescence (quantum yield 18 %). SQDs from sulfur were fabricated during 12 h heating only after etching by hydrogen peroxide. It has been established that the hydrogen peroxide is ineffective agent for SQDs syntheses from sodium thiosulfate (“bottom-up” technique).

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
