在过去的三十年中，金属硒化物和碲化物量子点（QDs）由于其广泛的应用被认为是最重要的纳米材料之一，包括照明、太阳能收集、光催化、生物标记、量子计算等。随着人们对量子点相关产品的需求不断增长，环保、节能、省时的合成功能金属硒化和碲化量子点的方法备受欢迎。本文在综述了含硫前驱体的合成研究进展的基础上，综述了金属硒化物和碲化物量子点的绿色合成方法的最新进展。本文首先简要介绍了金属硫系量子点的基本合成方法。然后，讨论了许多正在发展的胶体合成方法，重点介绍了无膦前体和水离子前体。最后，本文总结了合成方案存在的挑战和未来的展望。我们希望本文的综述能提供一些有启发性的信息，以促进这一领域的进一步发展。
During the past three decades, metal selenide and telluride quantum dots (QDs) have been deemed one of the most vital nanomaterials in virtue of their extensive applications, including lighting, solar harvesting, photocatalysis, biolabelling, quantum computing and so forth. With the growing demands for the QD-related products, environmental friendly, energy-efficient and timesaving approaches to synthesize functional metal selenide and telluride QDs are greatly welcome. On the basis of the development in synthesis of chalcogen precursors, this mini review summarizes the recent progress in the green methods for synthesizing metal selenide and telluride QDs. At first, the panorama of basic synthetic methodology of metal chalcogenide QDs is briefly introduced. Then, numerous evolving colloidal synthetic methods are discussed, highlighting the phosphine-free precursors and the aqueous ionic precursors. Finally, this review ends with remaining challenges and future prospects in synthetic schemes. We hope this review will provide some stimulating information to promote further advancement in this area.
