Aluminum Nanoparticles For Photobleaching Resistance Of Quantum Dots In Solution
Résumé
We investigated aluminum nanoparticles (2–20 nm) synthesized via ion reduction in alkane solvents. Extinction spectroscopy revealed UV-range plasmon resonances matching Mie theory. These nanoparticles enhanced quantum dot emission by 1.75 times and reduced photobleaching, absorbing emitted light. They hold promise as building blocks for nanophotonics and protecting emitters from degradation.
