  • 摘要: 增强荧光发射可以提高荧光检测灵敏度、提高LED的亮度,在提高发光器件性能方面具有重要意义。由于金属结构在增强局域场、增强荧光发射方面具有很好效果,而柔性电介质材料具有灵活的可弯曲性特性,本文提出一种由金属-电介质-金属(MDM)组成的柔性结构以增强荧光发射。利用时域有限差分方法系统研究了该结构对量子点定向发射增强的影响。理论计算表明柔性MDM结构局部起伏和弧度对荧光增强起促进作用,且可以使位于结构中心位置量子点的量子效率增强约7倍。此外,还可以改变电介质的折射率和厚度从而实现目标波长的可调谐性。实验结果表明该柔性MDM结构对荧光增强有一定的促进作用,这一发现对未来的显示技术和柔性发光器件都有很大的价值,对高效柔性器件的开发应用具有一定的指导意义。
