Multiphoton upconversion in rare earth doped nanocrystals for sub-diffractive microscopy

(author unknown)



L. Caillat, B. Hajj, and V. Shynkar et al.

A major bottleneck in microscopic imaging is the limited lateral resolution due to the diffraction of light. To overcome this limit, here we demonstrate the upconversion process in rare earth doped nanoparticles (RE:NPs), which may serve as an original fluorescence-source mechanism. RE:NPs have be ...
