Abstract
Abstract In this work, the phosphors of Eu3+ ions doped Ba2.9Sr0.1WO6 were successfully synthesized by the high-temperature solid-state method. The luminescence properties, including the emission and excitation spectra, fluorescent lifetimes, and CIE chromaticity coordinates were characterized. The crystal structure and composite of the samples were investigated by XRD (X-ray diffraction), and HRTEM (high-resolution transmission electron microscope). The emission spectra consist of the characteristic peak of Eu3+ excitation at 393 nm; the leading emission peak at 618 nm can be ascribed to the transition of 7F0 → 5L6. The optimal red emission is achieved by 2 % Eu3+ doping. This red Ba2.9Sr0.1WO6: Eu3+ has good luminescent properties and may have potential application in white LEDs.
