Abstract

Rare earth doped luminescent materials can be used in fluorescent lamps, display devices, biology and many other fields. Especially, phosphors with controllable morphology and multicolor tunable luminescence have many virtues. Thus, the synthesis of suitable phosphors is very important. Among all the synthesis methods, hydrothermal method stands out. Europium activated terbium tungstate (Tb2 (WO4)3: Eu3+) phosphors with controllable morphology have been successfully synthesized by hydrothermal method, followed by a subsequent calcination process. X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL) are employed to characterize the samples. Controlling the reaction parameters, a variety of morphology have been obtained. Thanks to the efficient energy transfer from WO42- to Tb3+ to Eu3+, Tb2 (WO4)3: Eu3+ phosphors demonstrate outstanding luminescent properties with tunable colors under ultraviolet (UV) excitation, which makes it possible that the emission colors of Tb2 (WO4)3: Eu3+ phosphors can be altered from green, yellow, orange to red with the doped Eu3+ content increasing. The facile preparation route and multicolor tunable luminescence make the materials promising candidate phosphors applied in future color displays and light-emitting devices.
