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 ...
