What Information Can UV-Vis Spectroscopy Provide About Nanoparticles?
UV-Vis spectroscopy can provide several critical pieces of information about nanoparticles:
Particle size: The position and shape of absorption peaks can indicate the size of nanoparticles. Concentration: The intensity of the absorption peaks can be used to quantify the concentration of nanoparticles in a solution. Surface plasmon resonance (SPR): SPR peaks provide insights into the electronic properties and environment of metallic nanoparticles. Band gap: The onset of absorption can be used to estimate the band gap of semiconductor nanoparticles.
