Silicon nanoparticles (SiNPs) can be challenging to prepare with defined size, crystallinity, composition, and surface chemistry. As is the case for any nanomaterial, controlling these parameters is essential if SiNPs are to realize their full potential in areas such as alternative energy generation and storage, sensors, and medical imaging. Numerous teams have explored and established innovative synthesis methods, as well as surface functionalization protocols to control these factors. Furthermore, substantial effort has been expended to understand how the abovementioned parameters influence material properties. In the present review we provide a commentary highlighting the benefits and limitations of available methods for preparing silicon nanoparticles as well as demonstrations of tailoring optical and electronic properties through definition of structure (, crystalline amorphous), composition and surface chemistry. Finally, we highlight potential opportunities for future SiNP studies.
制备具有确定尺寸、结晶度、组成和表面化学性质的硅纳米颗粒（SiNPs）可能具有挑战性。与任何纳米材料一样，如果SiNPs要在替代能源生成与存储、传感器和医学成像等领域充分发挥其潜力，控制这些参数至关重要。许多团队已经探索并建立了创新的合成方法以及表面功能化方案来控制这些因素。此外，人们还付出了巨大努力来了解上述参数如何影响材料性能。在本综述中，我们进行了评论，强调了制备硅纳米颗粒的现有方法的优点和局限性，以及通过定义结构（晶体 非晶体）、组成和表面化学来定制光学和电子性质的示例。最后，我们强调了未来SiNP研究的潜在机会。
