What are the different techniques to take a reference when measuring scattering spectra of plasmonic nanoparticles in dark field configuration?

Hello, I am currently measuring dark field scattering spectra of gold nanoparticles/PVA (polymer) nanocomposites. The composite films are deposited on glass substrates. As the nanoparticules...

Is there a specific method to set a Mach Zehnder interferometer for surface relief grating inscription on polymer thin films?

Hello, I have built a Mach-Zhender interferomer in order to irradiate thin films of polymer (PMMA) with an interference pattern. These polymer thin films are doped with metallic precursors, and...

Could someone tell me approximately what are the right concentration and speed to fabricate PMMA film ranging form 1 to 5 microns by spin-coating?

I'm trying to spin-coat PMMA solutions (doped or not with various amount of gold salt) on glass substrates (1,5 cm^2). The PMMA was used as received (Aldrich, Mw=150000 by GPC) and dissolve in...

What is the solubility of the PAZO polymer (Poly[1-[4-(3-carboxy-4-hydroxyphenylazo)benzenesulfonamido]-1,2-ethanediyl, sodium salt]) in toluene?

In the end I want to spin-coat the polymer to fabricate a 100 nm thick film. However people usually work with methanol and it is important for me to use Toluene.
