Is it correct to use a refractive index of 0.25 for Cu when I'm analysing Cu nanopowder dispersions by dynamic light scattering?

09 September 2018 0 1K Report

The Malvern sample dispersion and refractive index guide states that the RI of copper is 0.25. Is this the correct value to use if I want to model copper nanopowder dispersions in methanol? I'm using a NanoS to analyse the samples.
