Abstract:Multimode emission of Mn 2+ for multimode fluorescence anticounterfeiting is achieved by cation site and interstitial occupancy in Ca 2−x Mg x Ge 7 O 16 . The rings in Ca 2−x Mg x Ge 7 O 16 have a significant distortion for Mn 2+ ions to enter the ring interstitials with a luminescence center at 665 nm, which is supported by XRD refinement results and first-principles calculations. The interstitial Mn 2+ ion has good thermal stability with an activation energy of 0.36 eV. Surprisingly, these two luminescence c… Show more
