Strong green emission has been obtained for Tb(III)-doped cerium phosphate single-crystalline nanorods synthesized via a facile, Pluronic P123 (EO20PO70EO20 Mav=5800, Aldrich)-assisted, hydrothermal method. The surfactant Pluronic P123 was found to play a crucial role in the enhanced photoluminescence emission as compared with the same material but synthesized without the surfactant. The smooth surface, well-defined facets, single crystalline feature, uniform morphologies, and especially very narrow size distributions (10–12 nm) of the Tb(III)-doped cerium phosphate single-crystalline nanorods are considered to be responsible for the strong photoluminescence emission.
