Abstract

Up-conversion is an anti-Stokes optical process that can emit ultraviolet/visible/near-infrared light by converting low-energy near-infrared excitation photon radiation. With the advent of nanotechnology and the inexpensive high-power infrared diode lasers, the rare earth-doped up-conversion luminescent nanoparticles have been extensively studied for its potential applications in various fields. In recent years, rare earth-doped up-conversion nanoparticles have been developed as a promising alternatives luminescent optical labels to organic fluorophores and quantum dots for applications in biological assays and medical imaging. The unique optical property of rare earth-doped up-conversion nanoparticles offers low autofluorescence, less scattering and absorption, and deep penetration in biological samples. In this chapter, we give a general introduction to rare earth up-conversion nanoparticles, including the rare earth up-conversion materials, up-conversion mechanisms, synthesis methods, surface modifications, optical properties tuning and so on.
