Abstract:
A series of double doped Sr2Al2SiO7 :Eu2+,Dy3+ is prepared by solid state reaction. Photoluminescence and thermoluminescence properties have been studied. Photoluminescence emission peak intensity has been increased after annealing the sample in reducing atmosphere. One broad peak is obtained at 505nm due to transition from 4f7 state to 4f65d1 excited state. TL peak is obtained at 89o C low temperature.
