FAM-810/1000-2 shows at 0.9-1.0 µm IR excitation
intensive Stokes 1.1 - 1.2 µm IR bands and reduced visible
FAM-810/1000-3 shows at 0.9-1.0 Ám IR excitation
intensive Stokes 1.4 - 1.7 Ám IR bands and reduced visible luminescence.
Both phosphors can be used in various IR light & image converters
and in luminescent marking with new set of visual & instrumentally
detecting security features.
