Abstract
The concentration quenching of persistent luminescence was investigated. SrAl2O4:Eu2+,Dy3+ was taken as an instance. We proposed a model to explain the phenomenon. The concentration quenching of Eu2+ is attributed to competitive capturing of electrons with traps, while the concentration quenching of Dy3+ is interpreted by electron tunneling among traps.
