Description
Summary:Optical properties of nanocrystals have the potential to drive the next generation of optoelectronic devices. However, a number of technological limitations remain to be overcome. Nanocrystals' emission is strongly impacted by the chemical environment and high excitation power. In this paper, we present a preparation route to hybrid core-shell nanoplatelets encapsulated in a gold silica shield. The induced plasmon coupling offers a higher brightness at high power excitation. We also detail the highly increased fluorescence stability offered by the silica-gold-shell protection against photobleaching processes. Optical properties of nanocrystals have the potential to drive the next generation of optoelectronic devices.
