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(4):Yb/Tm and NaYF(4):Yb/Er microrods and CaS:Eu(2+) afterglow phosphors. Under 975 nm excitation, the hybrid...
