Upconversion (UC) refers to nonlinear optical processes in which the
sequential absorption of two or more photons leads to the emission of
light at shorter wavelength than the excitation wavelength (anti-Stokes
type emission). In contrast to other emission processes based on
multiphoton absorption, upconversion can be efficiently excited even
at low excitation densities. The most efficient UC mechanisms are
present in solid-state materials doped with rare-earth ions. The
development of nanocrystal research has evoked increasing interest in
the development of synthesis routes which allow the synthesis of highly
efficient, small UC particles with narrow size distribution able to form
transparent solutions in a wide range of solvents. Meanwhile, highquality
UC nanocrystals can be routinely synthesized and their solubility,
particle size, crystallographic phase, optical properties and
shape can be controlled. In recent years, these particles have been
discussed as promising alternatives to organic fluorophosphors and
quantum dots in the field of medical imaging.
