Abstract

A series of monodisperse cruciate multilayer H₃Sr₆(PO₄)₅·2H₂O:Eu²⁺ microarchitectures assembled by crossed nanorods have been successfully synthesized via a facile surfactant-assisted hydrothermal route. XRD and FT-IR confirmed the existence of crystalline water in the phosphor. The FE-SEM images revealed that the phase and morphology of resulting samples were strongly depended on the optimization of the reaction conditions, especially the pH value and the molar ratio of citric acid (CA)/Cations. Furthermore, the possible growth mechanism of H₃Sr₆(PO₄)₅·2H₂O:Eu²⁺ microarchitectures was proposed in detail. Under near-ultraviolet excitation of 365 nm, the as-obtained H₃Sr₆(PO₄)₅·2H₂O:0.05Eu²⁺ sample exhibited intense wide characteristic blue emission of Eu²⁺, which could be decomposed by Gaussian fitting into two peaks corresponding to different Eu²⁺ luminous centers. The present results demonstrated that the morphology-tunable H₃Sr₆(PO₄)₅·2H₂O:Eu²⁺ microarchitecture could be used as a potential candidate for future optoelectronic device applications.
