The novel doped nanocrystals doped with terbium-doped ZnO nanocrystals were studied by photoluminescence, and the synergistic luminescence was observed. It was found that there was an effective energy transfer between the ZnO nanomatrix and the terbium doped into it. This energy transfer plays a decisive role in the characteristic luminescence of rare earth terbium ions
