## Description

- description: "Long persistent luminescence materials developed to commercial standards
    are primarily concentrated in the blue and green regions, with only a few in the
    red region. Red, as one of the three basic colors, can be mixed in various proportions
    with blue and green to yield various colors. The development of red persistent
    phosphors has a broader application potential but remains a challenge. A solid-state
    reaction method was used to synthesize new red persistent luminescent materials
    of Ba1-xSrxGa2O4:Sm3+ (x = 0–0.09). In BaGa2O4, both Sr2+ and Sm3+ preferentially
    occupy the Ba2+ site rather than the Ga3+ site. When exposed to UV light at 254
    nm, the phosphors emit the characteristic red emission of Sm3+ at wavelengths
    ranging from 500 nm to 750 nm. After removing the UV light source, an intense
    red afterglow that lasted more than 1400 seconds was observed. The red afterglow
    signal reappears after a heating process. Doping Sr2+ reduces the trap depth and
    improves the red persistent luminescence significantly. Because the escaped electrons
    from traps compensate for the emission loss of Sm3+ during the heating process,
    the red phosphors have unimaginably luminescent thermal stability. Thus, the emission
    intensity at 200 °C is 1.6 times that at room temperature. The prepared red persistent
    phosphors show multimode luminescence, with the output signal being time and temperature
    sensitive, indicating that they are potential luminescent materials for anti-counterfeiting
    applications. Finally, a building-block strategy for advanced anti-counterfeiting
    applications of dynamic display information is proposed, with red persistent phosphors
    serving as an important component combined with upconversion phosphors of NaYF4:Yb3+,
    Tm3+, and green persistent phosphors of SrAl2O4:Eu2+,Dy3+.\r\n"
