  • SizeDependent Materials Properties Toward a Universal Equation

  • nanoparticles of material show different properties compared to larger particles of the same Therefore the surface area to the volume ratio will be 4πr2/(4/3πr3) = 3/r Therefore, as particle size decreases, a greater proportion of the particles.

    Decrease of surface to volume ratio in spherical nanoparticles led to red-shift in SPR diagram.
