Summary:In this paper, novel EuSr2F7 and TbSr2F7 nanostructures were successfully synthesized via an ultrafast wet-chemical route at room temperature. The elemental compositions, morphology, luminescent behaviors, thermal stability, decay curves and quantum yields of the as-prepared samples were investigated. The fabricated white light-emitting diodes (WLEDs) exhibited excellent color rendering index and correlated color temperature values. The security inks and soft polydimethylsiloxane films were prepared for potential anti-counterfeiting and flexible display applications. Eventually, under low accelerating voltage and filament current, the as-prepared samples showed strong cathodoluminescence emission intensity. The above results suggest that the novel EuSr2F7 and TbSr2F7 nanostructures with outstanding luminescent performances could be promising for field-emission displays, WLEDs, flexible display films, and anti-counterfeiting applications.
