Area of Science:

  • Materials Science
  • Nanotechnology
  • Plasma Physics

Background:

  • Aluminum nanoparticles (Al NPs) possess unique size-dependent properties valuable for energetic and plasmonic applications.
  • Surface passivation is crucial to prevent native oxide formation, which degrades Al NP performance.
  • Plasma-based synthesis offers a controlled environment for nanoparticle modification.

Purpose of the Study:

  • To synthesize surface-modified aluminum nanoparticles (Al NPs) with tunable core-shell structures.
  • To investigate the effect of plasma parameters on nanoparticle morphology and composition.
  • To evaluate the enhanced thermal stability of the synthesized nanoparticles.

Main Methods:

  • Utilized radiofrequency (RF)-driven capacitively coupled argon/hydrogen plasma with aluminum trichloride (AlCl3) vapor and dilute silane (SiH4).
  • Varied RF power and SiH4 flow rate to control nanoparticle formation and surface modification.
  • Characterized nanoparticle morphology and composition using scanning transmission electron microscopy (STEM-HAADF) and energy-dispersive X-ray spectroscopy (EDS).
  • Performed thermal analysis to assess oxidation behavior.

Main Results:

  • Successfully produced various Al NP morphologies, including Al-SiO2 core-shell, Si-Al2O3 core-shell, and Al-Si Janus particles.
  • Demonstrated tunable Al-to-Si ratios in Al-SiO2 core-shell nanoparticles by adjusting plasma parameters.
  • Observed an increased oxidation temperature for Al-SiO2 core-shell particles (585 °C) compared to bare Al NPs (535 °C).

Conclusions:

  • All-gas-phase plasma synthesis provides a facile method for producing high-purity heterostructured Al NPs.
  • The developed method allows for controlled surface modification and tuning of nanoparticle properties.
  • The enhanced thermal stability of Al-SiO2 core-shell nanoparticles broadens their potential applications.
