Optical trapping reveals differences in dielectric and optical properties of copper nanoparticles compared to their oxides and ferrites
In a nanoplasmonic context, copper (Cu) is a potential and interesting surrogate to less accessible metals such as gold, silver or platinum. We demonstrate optical trapping of individual Cu nanoparticles with diameters between 25 and 70 nm and of two ionic Cu nanoparticle species, CuFe(2)O(4) and Cu...
