Nanoparticle Synthesis System Enables High Deposition Rate
Scaled-up System for Nanoparticle Deposition
Nanoparticles such as FeCo-FeCoO, FeCo-Au, FeCo-SiO2, Fe-Ag, Co-Au, C, Fe-Au are currently limited to laboratory scale production due to a lack of a system to produce these nanoparticles in large quantities. But a nanoparticle synthesis system has been designed that produces unique nanoparticles including gold shells with high crystallinity and high magnetic moment nanoparticles on an industrial scale, some of which are not possible to produce using other processes. A non-chemical, physical process using a sputtering target enables high-throughput performance. The nanoparticles may be utilized in industrial applications ranging from biomedical to solar and data storage applications.
The Nanoparticle Synthesis System Improves Gas-phase Condensation Techniques
The nanoparticle deposition system relies on a gas phase condensation technique based on a sputtering source. This nanoparticle deposition system involves four key improvements:
- A tube sputtering target design
- A new rotational magnetron
- A new nanoparticle collection setup and handling process, which enables continual collection of nanoparticles on a flexible substrate without breaking the vacuum to change the sputtering target
- A new multi-source nanoparticle deposition system, which will enable deposition of composite films with different nanoparticles
Together, these improvements enable high deposition rates for a class of both nanoparticles and superior morphology for nanoparticles capable of being produced via other methods.
