与Si纳米晶体相比，Si 1-xGex合金纳米晶体具有潜在的上级性质，例如增强的吸收截面和更宽的带隙能量可控性。然而，关于Si 1 −xGex合金纳米晶，特别是胶体Si 1 −xGex合金纳米晶的合成报道仍然非常有限，质量也不如胶体Si纳米晶高。在这里，我们报告了一种新型的发光胶体Si 1 −xGex合金纳米晶体的直径为3至6 nm的发展。Si 1-xGex合金纳米晶体的特征在于在表面上形成高B和P浓度层。壳提供无机原子配体，并且B和P共掺杂的Si 1 −xGex纳米晶体可以分散在醇中而无需任何表面官能化过程。
Si1−xGex alloy nanocrystals potentially have superior properties compared to Si nanocrystals such as an enhanced absorption cross-section and wider controllability of the band gap energy. However, reports on the synthesis of Si1−xGex alloy nanocrystals, especially colloidal Si1−xGex alloy nanocrystals, are still very limited and the quality is not as high as that of colloidal Si nanocrystals. Here, we report the development of a new type of luminescent colloidal Si1−xGex alloy nanocrystals of 3 to 6 nm in diameter. The characteristic feature of the Si1−xGex alloy nanocrystals is the formation of a high B and P concentration layer on the surface. The shell provides inorganic atomic ligands and B and P co-doped Si1−xGex nanocrystals can be dispersed in alcohol without any surface functionalization processes.
