研究了具有局域等离子共振特性的金纳米岛状结构阵列对高分子材料共混体系中激发复合体荧光发射特性的影响.实验结果表明,当粒子等离子共振发生在激发复合体荧光光谱区时,其荧光发射的强度得到了显著增强,且荧光寿命也得以延长.可以认为,粒子等离子共振诱发的局域场增加了激子的扩散距离,利于在相分离界面处激发复合体的形成.

We investigate in this paper the influence of the localized plasmon resonance of gold nano-island structure on the photoluminescence of the exciplex in the polymer blends. The experimental results show that when the particle plasmon resonance overlaps the photoluminescence spectrum of the exciplex,the corresponding emission intensity is enhanced significantly. Furthermore, alonger lifetime is observed with the exciplex emission. We propose that the localized electrical field induced by the particle plasmon resonance increaseds the exciton diffusion length and thus conduces to the formation of the exciplex in the phase separation interface.-
