Resumen
We report shell-isolated nanoparticle-enhanced fluorescence (SHINEF) of CdTe quantum dots. Enhanced
spectra are obtained after Ag SHINs were spread onto homogenous CdTe quantum dot/polyelectrolyte
layer-by-layer (LbL) films on quartz. The thin silica shell of the SHINs effectively isolates the Ag cores,
preventing short-range quenching to the metal and enabling plasmon enhancement of the quantum dot
fluorescence (ca. 35 fold)
