We report the distance-dependent energy transfer from an InGaN quantum well to graphene oxide (GO) by time-resolved photoluminescence (PL). A pronounced shortening of the PL decay time in the InGaN quantum well was observed when interacting with GO. The nature of the energy-transfer process has been analyzed, and we find the energy-transfer efficiency depends on the 1/d² separation distance, which is dominated by the layer-to-layer dipole coupling.
我们通过时间分辨光致发光（PL）报告了从 InGaN 量子阱到氧化石墨烯（GO）的距离依赖能量转移。当与 GO 相互作用时，观察到 InGaN 量子阱中 PL 衰减时间明显缩短。我们分析了能量转移过程的性质，发现能量转移效率取决于 1/d² 分离距离，这主要由层间偶极耦合决定。
