Improving Upconversion Efficiency by Photon Management in Self-Assembled Core/Shell Nanocrystal Films

We present the synthesis of Er-doped NaYF4/NaLuF4 core/shell nanocrystal films, which enable optical upconversion of photons from a wavelength of 1500 nm into photons of a wavelength of 980 nm. Combining such films with specially tailored Au nanostructures and a Au back-reflector, it is demonstrated...
