What Information Can UV-Vis Spectrophotometry Provide About Nanomaterials?
UV-Vis spectrophotometry can provide a variety of information about nanomaterials, including:
Particle Size: The position and shape of the absorbance peak can be correlated to the size of the nanoparticles. Concentration: The intensity of the absorbance can be used to determine the concentration of nanoparticles in a solution. Aggregation: Shifts in the absorbance peak can indicate aggregation or changes in the dispersion state of nanoparticles. Surface Plasmon Resonance: For metallic nanoparticles, the absorbance peak can give information about the surface plasmon resonance, which is sensitive to the particle's size, shape, and surrounding environment.
