The decay kinetics of GdAlGaO:Ce single crystal luminescence were studied under dense laser excitation. It was shown that the decay times as well as the intensity of Ce 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. The numerical simulation of the experimental results was performed for justification of the proposed model.
在强激光激发下研究了GdAlGaO:Ce单晶发光的衰减动力学。结果表明，Ce发光的衰减时间和强度均取决于激发密度。观察到的效应归因于激子之间的相互作用以及从激子到Ce的能量转移特征。对实验结果进行了数值模拟，以验证所提出的模型。
