title: Prevention of self-quenching in fluorescent silica nanoparticles by efficient energy transfer.
abstract: Stars that shine bright: A high local dye concentration in doped silica-based core–shell nanoparticles causes self-quenching and spectral broadening (top images). This phenomenon jeopardizes the potential advantages of heavily doped systems. Förster resonance energy transfer (FRET) to an acceptor co-included in the silica led to ultrabright nanoparticles (bottom images) with a preselected narrow-band emission and a pseudo-Stokes shift of 129 nm.
