Article Synopsis
- Aliovalent-doped metal oxide nanocrystals with localized surface plasmons (LSPRs) are essential for applications requiring specific optical properties, particularly between infrared and visible light transparency.
- Indium tin oxide (ITO), while dominant in this area, is limited by scarce indium resources, leading researchers to explore antimony-doped tin oxide (ATO) as a cost-effective alternative, despite its less favorable electronic characteristics and challenges in controlling LSPRs.
- This study presents a method to synthesize plasmonic ATO nanocrystals using a solvothermal approach, demonstrating that ligand exchange can effectively tune LSPR energies and enhance doping efficiency beyond traditional methods, opening doors for various applications like infrared upconversion and thermal management.
Successful formation of electronic interfaces between living cells and semiconductors hinges on being able to obtain an extremely close and high surface-area contact, which preserves both cell viability and semiconductor performance. To accomplish this, we introduce organic semiconductor assemblies consisting of a hierarchical arrangement of nanocrystals. These are synthesised via a colloidal chemical route that transforms the nontoxic commercial pigment quinacridone into various biomimetic three-dimensional arrangements of nanocrystals.
