Study Notes
Surface Plasmon Resonance
- Incident light striking a metal surface at a specific angle generates surface plasmon resonance, causing collective oscillations of electrons at the surface.
Interaction of Incident Radiation with Metal Nanocrystals
- When the size of a metal nanocrystal is larger than the wavelength of incident radiation, the radiation scatters off the nanocrystal.
Color Determination in Surface Plasmon Resonance
- The color of a material in surface plasmon resonance is determined by the specific wavelengths of light that are absorbed or scattered by the material.
Nanoparticles and Specific Wavelengths of Light
- Nanoparticles can absorb or scatter specific wavelengths of light, resulting in unique optical properties.
- This interaction between nanoparticles and incident light can lead to selective absorption or emission of certain wavelengths, influencing the material's color.
