What does UV-Vis spectroscopy measure?
Think about how light interacts with substances.
Name one characteristic of nanoparticles that UV-Vis can detect.
What happens to light when it hits small particles?
What does UV-Visible Spectroscopy measure?
Remember the full name of the technique!
True or False: Quantum confinement effects are more pronounced in larger nanoparticles.
Think about how size affects the properties.
If you synthesized gold nanoparticles and observed a shift in the absorption peak from 520 nm to 550 nm, what does this indicate about your nanoparticles?
Relate the wavelength shift to size changes.
How would you design an experiment using UV-Vis spectroscopy to optimize the synthesis of a new type of nanoparticle?
Think about the relationship between color and particle properties as you synthesize.
