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.
Article Synopsis
- Small scratches and abrasions in packaging coatings can lead to significant negative effects, allowing gases to penetrate and degrade sensitive products.
- The study introduces color-changing particles that signal mechanical damage in coatings, utilizing a core-shell structure with distinct colors in the core and shell.
- When the coating is damaged, the particles change color, allowing for real-time monitoring of damage and potential oxygen penetration in the coating.
