研究了CdSe/CdS核/壳量子点、纳米棒和四脚体的光致发光随流体静压和非流体静压的变化。所有三种微结构的光电性能都受到应变的影响。此外,它表明,种子四足动物的独特形态是高度敏感的非各向同性应力环境。因此,种子四脚体可以用作光学应变计,能够测量纳米牛顿量级的力。我们预计,一个具有光学读出的应变计将是有用的应用,包括敏感的光学机械设备和生物力的调查。
The photoluminescence of CdSe/CdS core/shell quantum dots, nanorods, and tetrapods is investigated as a function of applied hydrostatic and non-hydrostatic pressure. The optoelectronic properties of all three nanocrystal morphologies are affected by strain. Furthermore, it is demonstrated that the unique morphology of seeded tetrapods is highly sensitive to non-isotropic stress environments. Seeded tetrapods can thereby serve as an optical strain gauge, capable of measuring forces on the order of nanonewtons. We anticipate that a nanocrystal strain gauge with optical readout will be useful for applications including sensitive optomechanical devices and biological force investigations.
