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 NaYF4:Yb/Tm and NaYF4:Yb/Er microrods and CaS:Eu2+ afterglow ph

The fluorescence intensity ratio (FIR) technique is widely adopted in thermometric phosphor materials, but the improvement of relative sensitivity is normally limited by the fixed energy gap between two thermally-couped emitting levels of luminescent

Broadband sensitization is an effective strategy to enhance the upconversion luminescence (UCL) of lanthanide ions. Herein, novel UC materials LiScSi2O6:Cr3+/Er3+ (LSS:Cr3+/Er3+) were synthesized by high-temperature solid state reaction and their lum

This study presents a novel and high-level anticounterfeiting strategy based on Ce/Yb/Ho triply-doped NaGdF4 nanocrystals with temperature-responsive multicolor emission. A critical factor leading to the multicolor emission is confirmed by comparing
