Upconversion Enhancement in Lanthanide-Doped Nanoparticles Using Nanoplasmonics
Upconversion is a process in which the sequential absorption of two (or more) low-energy photons leads to the emission of one photon with higher energy. The upconversion process can occur in materials such as lanthanide-doped nanoparticles and can be enhanced by the strong local electric field found in the proximity of metallic (plasmonic) nanostructures.
Nanomaterials have attracted considerable attention due to their size-dependent properties, allowing many interesting and sometimes novel features to be observed . Of particular interest are luminescent nanoparticles as they have been touted to find widespread integration in applications ranging from the realization of display devices to bioimaging . One particular class of luminescent nanomaterials that has garnered considerable interest is the lanthanide (Ln3+)-doped upconverting nanoparticles (UCNPs). These UCNPs are...
