Surfactant-assisted synthesis of Tb(Ⅲ)-doped cerium phosphate single-crystalline nanorods with enhanced green emission

摘要

Strong green emission has been obtained for Tb(Ⅲ)-doped cerium phosphate single-crystalline nanorods synthesized via a facile, Pluronic P123 (EO_(20)PO_(70)EO_(20) M_(av)=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 (10-12nm) of the Tb(Ⅲ)-doped cerium phosphate single-crystalline nanorods are considered to be responsible for the strong photoluminescence emission.
