I am a beginner in the synthesis and characterization of metal nanomaterials. I am trying to figure out what information of the nanomaterials can be obtained by UV-Vis spectra.
Molar extinction coefficient (the capacity to absorb); aggregation state of nanoparticles; size of nanoparticles; number of species in equilibrium (isosbestic points); band gap....
size of nanoparticles, colloidal stability vs aggregation, concentration, loading of guest moieties such as dyes, catalytic activity of nanopartilcles for some reactions such as conversion of p-nitrophenol to p-aminophenol by gold nanoparticles....
