Ep21 Nanobiophotonics, SPR, absorption, scattering. UCSD, NANO 11/101, Darren Lipomi

Introduction to nanobiophotonics. CORRECTION: Copper and gold actually have plasma frequencies higher than the visible range, so this does not play a role in their color. Instead, their color is thought to originate from relativistic effects which result in a change to the masses of the electrons. This deviation subsequently changes the energies of some relevant d and s orbitals, enabling optical transitions between them in the visible range. Interestingly: Cesium's carrier density is a whole order of magnitude lower than gold or copper, and its color does seem to result from its plasma frequency :) (Correction courtesy of Guillermo Esparza, thanks!)  http://lipomigroup.org
