A commercially available blue persistent phosphor was analyzed using thermoluminescence in the new General Order Kinetics formalism. From the analysis, it is seen that the TL curve of a blue persistent phosphor can be described by seven TL peaks with the activation energy ranging from 0.666-1.14 eV. The frequency factor is in the range from 108-109 sec−1. The value of η is the range of 0.012≤η≤0.154, which suggests that about 1-15% of the empty traps takes part in the retrapping of electrons from the conduction band. Again, from the ratio of N/no it is seen that the material consists of abundant empty traps. The luminescence lifetime of the blue persistent luminescent material Sr4Al14O25:Eu2+Nb3+ ranges from 0.65hr to 1.3 x 108 hrs at 300°K. The persistence luminescence of Sr4Al14O25:Eu2+Nb3+ at room temperature is due to the trap at 362.9°K.
