Decay Kinetics of Gd(3)Al(2)Ga(3)O(12):Ce(3+) Luminescence under Dense Laser Irradiation

The decay kinetics of Gd(3)Al(2)Ga(3)O(12):Ce(3+) single crystal luminescence were studied under dense laser excitation. It was shown that the decay times as well as the intensity of Ce(3+) luminescence depend on the excitation density. The observed effects were ascribed to the interaction between e...

Sumario:The decay kinetics of Gd(3)Al(2)Ga(3)O(12):Ce(3+) single crystal luminescence were studied under dense laser excitation. It was shown that the decay times as well as the intensity of Ce(3+) luminescence depend on the excitation density. The observed effects were ascribed to the interaction between excitons as well as to the features of energy transfer from the excitons to Ce(3+). The numerical simulation of the experimental results was performed for justification of the proposed model.
