Ethylene glycol-assisted ultrafast synthesis and luminescent properties of novel multifunctional EuSr2F7 and TbSr2F7 nanostructures for WLEDs, displays and anti-counterfeiting

Ce3+/Tb3+‐coactived NaMgBO3 phosphors toward versatile applications in white LED, FED, and optical anti‐counterfeiting

“…As is known, rare‐earth‐activated phosphors have been considered as potential candidates for optical anti‐counterfeiting due to their multi‐mode emission properties and high stable emission characteristic 59,60 . To evaluate the potential application of the prepared samples in anti‐counterfeiting, the NaMgBO 3 :0.01Ce 3+ ,0.03Tb 3+ phosphor and UV curable epoxy were fully mixed together so as to obtain anti‐counterfeiting composites, as shown in Figure .…”

After that, the anti-counterfeiting patterns were drawn on the experimental weighing paper and solidified using the composites and they were completely dried under 254 nm UV lamp irradiation, as shown in Figure 10.…”
