%J 中国物理快报 %D 2009 %I %X The inter-layer energy transfer in a bi-layer InGaAs/GaAs quantum dot structure with a thick GaAs barrier is studied using temperature-dependent photoluminescence. The abnormal enhancement of the photoluminescence of the QDs in the layer with a larger amount of coverage at 110K is observed, which can be explained by considering the resonant F rster energy transfer between the wetting layer states at elevated temperatures. %K 73 %K 63 %K Kv %K 78 %K 67 %K -n %K 78 %K 55 %K Cr %K 73 %K 40 %K Gk %K 78 %K 55 %K -m
