抄録

Persistent phosphors show contentious luminescence even after ceasing excitation light. This unique phenomenon is caused by several processes such as carrier generation, trapping and detrapping. Based on the mechanism, persistent luminescence can be designed by controlling the carrier transportation. By utilizing the vacuum referred binding energy diagram of lanthanoid and transition metal ions for the prediction of the trap levels in host compounds, new persistent phosphors have been developed successfully. This design guides for persistent phosphors are introduced, and the analyzing methods for persistent phosphors are also explained.
