Mingyu Kwak

You no longer have nano particles in a film. There are no free, discrete, independent particles < 100 nm.

Xuhua Wang

Dear Mingyu Kwak,

You can measure the indium films using a UV-Vis spectrophotometer to check the plasmonic peaks. As Alan mentioned, the size of nano particles should be less than 100nm.

Alternatively you can easily check your nanoparticles under a microscope.

If I make the film with polymer and particle, Can't I see the surface plasmon resonance peak?

I mean does polymer effect to surface plasmon resonance?
