Abstract

Strong reddish-orange-emitting (Sr,Ba)₂YTaO₆:Eu³⁺ phosphors were synthesized via a facile solid-state reaction. Due to the occupation of Y³⁺ ions in the high symmetry (Oh) sites as an inversion symmetry site, the ⁵D₀ → ⁷F₁ magnetic dipole transition peak was dominant in the (Sr,Ba)₂YTaO₆:Eu³⁺ phosphors under the charge transfer band excitation. Both Sr₂YTaO₆:Eu³⁺ (SYTO:Eu³⁺) and Ba₂YTaO₆:Eu³⁺ (BYTO:Eu³⁺) phosphors exhibited good thermal stability and quantum yield. Their luminescence sensing performances (relative sensing sensitivity) were determined to be 0.18% K⁻¹ (BYTO:0.1Eu³⁺) and 0.13% K⁻¹ (SYTO:0.1Eu³⁺) with the aid of the Struck and Fonger models. Furthermore, novel deep ultraviolet-excited phosphors-based polydimethylsiloxane flexible light-emitting films were fabricated for anti-counterfeiting applications. Consequently, this work reveals that the strong reddish-orange-emitting (Sr,Ba)₂YTaO₆:Eu³⁺ phosphors are suitable for dual-functional applications including luminescence lifetime thermometry and flexible anti-counterfeiting labels.
