Fundamentals and Applications of Upconverting Nanoparticles
Upconverting nanoparticles upconverting nanocrystals are a unique class of materials that exhibit the intriguing property of converting near-infrared light into higher energy visible or ultraviolet light. This phenomenon, known as upconversion, arises from the absorption of multiple low-energy photons and their subsequent recombination to produce a single high-energy photon. The underlying mechanism involves a sequence of energy transitions within a nanoparticle's structure, often facilitated by rare-earth ions such as ytterbium and erbium.
This remarkable property finds wide-ranging applications in diverse fields. In bioimaging, ucNPs can as efficient probes for labeling and tracking cells and tissues due to their low toxicity and ability to generate bright visible fluorescence upon excitation with near-infrared light. This minimizes photodamage and penetration depths. In sensing applications, ucNPs can detect analytes with high sensitivity by measuring changes in their upconversion intensity or emission wavelength upon binding.
