Application
Upconversion nanoparticles (ucnps), are the result of a unique optical process in which near-infrared (NIR) light excitation is converted into visible and/or UV emission. Upconversion (UC) utilizes sequential absorption of multiple photons utilizing both lifetime and real ladder-like energy levels of ions in a host lattice to produce a higher energy anti-Stokes luminescence. This optical features of UCNPs, results in deep tissue penetration and minimal autofluorescence background, for a broad range of applications of UCNP in diagnostics and biomedical imaging systems.

Lanthanide-doped upconversion nanoparticles (UCNPs) are capable of converting near-infra-red excitation into visible and ultraviolet emission. Their unique optical properties have advanced a broad range of applications, such as fluorescent microscopy, deep-tissue bioimaging, nanomedicine, optogenetics, security labelling and volumetric display. However

Upconversion nanoparticles (UCNPs) convert near-infrared into visible light at much lower excitation densities than those used in classic two-photon absorption microscopy. Here, we engineered <50 nm UCNPs for application as efficient lanthanide resonance energy transfer (LRET) donors inside living cells. By

Imaging at the single-molecule level reveals heterogeneities that are lost in ensemble imaging experiments, but an ongoing challenge is the development of luminescent probes with the photostability, brightness and continuous emission necessary for single-molecule microscopy. Lanthanide-doped upconverting nanoparticles overcome problems

Lanthanide-doped glasses and crystals are attractive for laser applications because the metastable energy levels of the trivalent lanthanide ions facilitate the establishment of population inversion and amplified stimulated emission at relatively low pump power. At the nanometre scale, lanthanide-doped upconversion
