Single-Mode-Tuned Tricolor Emissions of Upconversion/Afterglow Hybrids for Anticounterfeiting Applications
This work presents a highly secure anticounterfeiting strategy based on upconversion/afterglow hybrids with tricolor emissions tuned by a single 975 nm laser. The hybrids are composed of NaYF<sub>4</sub>:Yb/Tm and NaYF<sub>4</sub>:Yb/Er microrods and CaS:Eu<sup>2+</sup> afterglow phosphors. Under 97...
