Facile synthesis and luminescent properties of LaPO4: Eu3+, Sm3+ nanorods via a designed two-step hydrothermal method

► LaPO4: Eu3+, Sm3+ nanorods have been successfully prepared by a designed two-step hydrothermal method. ► The doped Sm3+ was found to be efficient to sensitize the emission of Eu3+. ► The doped Sm3+ extend the absorption of near-UV light with wavelength of 400-405 nm.
