Luminescent properties of GdPO4:Eu nanorods

Highly luminescent GdPO₄:Eu³⁺ nanorods with hexagonal and monoclinic structures were successfully synthesized by a hydrothermal method. Results are shown that the prepared GdPO₄:Eu has a hexagonal or monoclinic structure under different synthetical process. The properties of the Eu³⁺-doped GdPO₄ nanorods were characterized by XRD, SEM and UV–vis spectroscopy. A study of the photoluminescence of Eu³⁺-doped GdPO₄ has revealed that the optical properties of these nanophosphors are strongly dependent on their crystal structures and morphologies.
