VRBE and HRBE schemes of lanthanides: design of dual-luminescence-center long persistent luminescence phosphors with Pr3+ or/and Tb3+ doping in Mg3Y2Ge3O12 garnet with high storage capacity for anti-counterfeiting, information storage, and X-ray imaging

The theoretical HRBE and VRBE scheme of Mg 3 Y 2 Ge 3 O 12 :Ln 3+ phosphors were constructed and applications in X-ray imaging, anti-counterfeiting and information storage realized, providing a basis for the rational design of novel long persistent luminescence and storage phosphors.
