Metal oxides, when electronically doped with oxygen vacancies, aliovalent dopants, or interstitial dopants, can exhibit metallic behavior due to the stabilization of a substantial charge carrier concentration within the material. As a result, localized surface plasmon resonances (LSPRs) occur in nanocrystals of conducting metal oxides. Through deliberate choice of both the host material and the defect, these resonances can be tuned across the entirety of the near- and mid-infrared regions of the electromagnetic spectrum. Optical modeling has revealed that the defects present have profound impacts on charge carrier mobility and electronic structure, and in some cases, choosing one dopant over another is an important trade-off for optimizing plasmonic performance. These materials are distinct from classical metals in that one can tune their LSPR in energy and intensity through their elemental composition independently of any particular size or nanocrystal morphology. In addition, the LSPR in these materials...

金属氧化物纳米晶体中局部表面等离子体共振的控制

金属氧化物，当用氧空位、异价掺杂剂或间隙掺杂剂进行电子掺杂时，由于材料内大量电荷载流子浓度的稳定性，可以表现出金属行为。结果，局部表面等离子体共振（LSPR）发生在导电金属氧化物的纳米晶体中。通过对主体材料和缺陷的慎重选择，这些共振可以在电磁波谱的整个近红外和中红外区域进行调整。光学建模表明，存在的缺陷对电荷载流子迁移率和电子结构具有深远的影响，在某些情况下，选择一种掺杂剂而不是另一种掺杂剂是优化等离子体性能的重要权衡。这些材料与经典金属的不同之处在于，人们可以通过其元素组成独立于任何特定尺寸或纳米晶体形态来调整其 LSPR 的能量和强度。此外，这些材料中的 LSPR...
