Claims9
A method for producing a nanoparticle assembly, comprising:
- mist generation in which a solution containing a nanoparticle is prepared and mist of the solution is generated;
- plasma generation in which a plasma is generated between a first electrode and a second electrode;
- and
- nanoparticle assembly production in which the mist is supplied between the first electrode and the second electrode and in which a nanoparticle assembly is generated,
- wherein, in the plasma generation, the plasma has a ratio of emission intensities (I391/I357) of 0.072 or more and less than 0.08, where I391 is an emission intensity at a wavelength of 391 nm and I357 is an emission intensity at a wavelength of 357 nm,
- the nanoparticle has an average primary particle size of 60 nm or less, and
- the nanoparticle assembly has a diameter of more than 500 nm to 5 μm or less.
