Abstract

CePO₄ nanorods decorated with QDs (QDs@CePO₄) can be prepared in a sequential, aqueous procedure under continuous flow using a rotating tube processor and a narrow channel reactor. The emission from the QD@CePO₄ is tunable from green to red by simply adjusting the feeding rate, which in turn regulates the particle size of the QDs. The Ce³⁺ ions in the QDs@CePO₄ serve as an efficient fluorescence resonance energy transfer (FRET) donor, effectively enlarging the Stokes shift of the QDs.
