Abstract
Composite plasmonic structures consisting of gold nanoparticles and carbon nanodots (CDs) in mesoporous silica particles have been synthesized. It has been established that the visible photoluminescence of CDs in these structures is three times more intense than that in analogous structures free of gold nanoparticles.
