Abstract

Red/near-infrared/short-wave infrared multi-band persistent phosphors are developed by doping Pr³⁺ into MgGeO₃ and CdSiO₃ hosts, which emit intense, very-long-lasting (>120 h) persistent luminescence at around 625 nm, 900 nm and 1085 nm after ultraviolet light excitation. The penetration power of these three wavelengths in chicken breast follows the order of 1085 nm > 900 nm > 625 nm.
