英文摘要	Trap filling studies of persistent phosphors using visible-light excitation have important implications on both fundamental luminescence research and practical applications. We report here an up-conversion charging (UCC) design of Gd3Ga5O12:Pr3+ persistent phosphor upon excitation with blue lasers. As an example, long-lasting emission from Pr3+ has been achieved in the phosphor after the traps are filled by subsequently absorbing two 450 nm excitation photons from a blue diode laser. Spectroscopic investigations reveal that the composition of UCC intermediate state is predominantly that of P-3(0) state of Pr3+ in the phosphor. Our work provides a major step toward developing the UCC design, which enables new properties of persistent luminescence to be discovered and new applications of persistent phosphors developed.
