Silver dendritic (“fractal”) structures exhibit very high fluorescence enhancement, but their nonuniformity limits practical applications. Here, we present a novel, electroless deposition approach to produce uniform silver dendritic nanostructure

We present a study of depolarized light scattering from gold nanoparticles of various shapes and heterodispersity in aqueous solutions. The light scattering anisotropy for particles with average aspect ratio ∼1.2 and above 1.5 was measured experime

ZnS nanocrystals (NCs) capped with tetramethylammonium (TMAH) were synthesized from ZnCl2 · 2H2O and thiourea using a wet chemical process. Further treatments of the nanocrystals such as aging, and annealing have been conducted to examine the stabil

Amplification of fluorescence is a nanoscale phenomenon which is particularly pronounced in close proximity to metal nanostructures. Due to its sharp distance dependence, it is ideally suited to monitor biorecognition reactions. Using this effect we

Intra-shell transitions of transition metal and rare earth ions are parity forbidden processes. For Mn2+ ions this is also a spin forbidden process, i.e., light emission should be inefficient. Surprisingly, it has been reported that in nanostructures
