What Information Can Be Gained from UV Spectroscopy in Nanotechnology?
UV spectroscopy can provide several key pieces of information about nanomaterials:
Band Gap Energy: The absorption edge in the UV-Vis spectrum can determine the band gap energy of semiconductor nanomaterials. Particle Size: The spectral features can be correlated to the size of nanoparticles, helping in the analysis of quantum dots and other nanostructures. Concentration: The Beer-Lambert law can be used to determine the concentration of nanomaterials dispersed in a solution. Surface Plasmon Resonance: For metallic nanoparticles, UV-Vis spectroscopy can identify surface plasmon resonance, which is influenced by particle size, shape, and environment.
