Bright dots : Semiconducting polymer dots (Pdots) doped with europium complexes possess line‐like fluorescence emission, high quantum yield, and long fluorescence lifetime. The Pdots successfully labeled receptors on cells. The long fluorescence lifetime of the Pdots was used to distinguish them from other red fluorescence emitting nanoparticles, and improve the signal‐to‐noise ratio for time‐gated cellular imaging. PVK=poly(9‐vinylcarbazole).
