Over 1000-fold enhancement of upconversion luminescence using water-dispersible metal-insulator-metal nanostructures
Upconversion nanoparticles are already used in bio-imaging but still suffer from low luminescence. Here, metal-insulator-metal nanostructures with 1-2 orders magnitude enhancement in upconversion are introduced enabling bioimaging at reduced particle or excitation power densities, respectively.
