Assembly of inorganic semiconductor nanocrystals into polymer host is of great scientific and technological interest for bottom-up fabrication of functional devices. Herein, an interface-directed synthetic pathway to polymer-encapsulated CdTe quantum dots (QDs) has been developed. The resulting nanohybrids have a highly uniform fibrous architecture with tunable diameters (ranging from several tens of nanometers to microscale) and enhanced optical performance. This interfacial assembly strategy offers a versatile route to incorporate QDs into a polymer host, forming uniform one-dimensional nanomaterials potentially useful in optoelectronic applications.
将无机半导体纳米晶组装到聚合物主体中对于自下而上制造功能器件具有重要的科学和技术意义。在此,开发了一种将聚合物包覆的 CdTe 量子点 (QD) 进行界面导向合成的方法。所得纳米杂化物具有高度均匀的纤维状结构,且直径可调(从几十纳米到微米级),并具有增强的光学性能。这种界面组装策略为将 QD 掺入聚合物主体中提供了一种通用途径,形成了均匀的一维纳米材料,在光电子应用中具有潜在的用途。
