• than twice that of the single nanorod for gaps larger than 220 nm, see Figure 3. Note that, if the local field enhancement is negligible (equal to unity), then the highest possible SHG from a dimer is 4 times that of the single nanorod, since SHG is a coherent optical process. The slight modulation of

Another group of highly photostable NP are lanthanide-doped upconversion NP (UCNP). Upconversion is an optical process in which the sequential absorption of two or more photons leads to the
