Focusing on the improvement of persistent duration, we used photoluminescence and thermally stimulated luminescence measurements to study the influence of different codopants M3+ (M3+ = Tm3+, Ga3+, Pr3+, Yb3+, Nd3+) on the luminescent quantum efficiency and traps distribution of Cr3+-doped stannate-baded long persistent phosphors (Zn2SnO4:Cr3+). This work reveals that Tm3+ is the most suitable codopant for enhancing the luminescent intensity and providing optimal trap depth for room temperature afterglow. This afterglow dependency toward the luminescent quantum efficiency of activator and traps distribution in host give us an important enlightenment, that is, when setting up a strategy of designing a long persistent phosphor, it is must integrally investigate the influence of these two factors.
