Abstract

Metal-enhanced fluorescence carbon dots adsorbed Ag@SiO2 composite nanoparticles, where the silica-shell is used to control the distance between silver-core and fluorescent carbon dots (CDs). A more than four-fold increase of fluorescence intensity of CDs was obtained, besides, a largely enhanced upconversion property was also observed.
