The synthesis of Group 14 nanocrystals with controlled size dispersity and composition is an area of considerable interest due to their size-dependent optical and electronic properties, thought to enable their use in a wide range of applications such as fluorophores for biological imaging and photovoltaics. In this review, the use of sol-gel derived polymers as precursors for oxide-embedded Group 14 nanocrystals is presented. This versatile approach can yield tangible quantities of both oxide-embedded and freestanding materials with controllable size, narrow size distributions, and tailorable composition.
由于其尺寸依赖性的光学和电子特性，合成具有可控尺寸分散性和组成的第 14 族纳米晶体是一个非常有趣的领域，这被认为使它们能够在各种应用中使用，例如生物成像的荧光团和光电。在这篇综述中，介绍了使用溶胶-凝胶衍生的聚合物作为氧化物嵌入的第 14 族纳米晶体的前体。这种多功能的方法可以得到大量的氧化物嵌入和自由-standing 材料，具有可控的尺寸、窄的尺寸分布和可调整的组成。
