How to Design and Analyze Persistent Phosphors?

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 can be designed controlling transportation. By utilizing vacuum referred binding energy diagram of lanthanoid transition metal ions for prediction trap levels in host compounds, new have been developed successfully. design guides are introduced, analyzing methods also explained. Until now through trial-and-error experimental procedure. In this study, we successfully develop based guide using biding diagram.
