Nonradiative energy transfer from an InGaN quantum well to Ag nanoparticles is unambiguously demonstrated by the time-resolved photoluminescence. The distance dependence of the energy transfer rate is found to be proportional to 1/d(3), in good agreement with the prediction of the dipole interaction calculated from the Joule losses in acceptors. The maximum energy-transfer efficiency of this energy transfer system can be as high as 83%.
通过时间分辨光致发光，明确地证明了 InGaN 量子阱到 Ag 纳米粒子的非辐射能量转移。发现能量转移速率的距离依赖性与 1/d(3)成正比，与从受体焦耳损耗计算的偶极相互作用的预测非常吻合。该能量转移系统的最大能量转移效率可达 83%。
