我们研究了等离子体增强荧光从CdSe/CdS/CdZnS/ZnS核/壳量子点附近的各种银和Au纳米粒子。量子点的光致发光激发（PLE）光谱紧密跟随纳米颗粒的局域表面等离子体共振（LSPR）散射光谱。我们测量的激发增强因子类似于3至10不同形状的单一金属纳米粒子。
We study plasmon-enhanced fluorescence from CdSe/CdS/CdZnS/ZnS core/shell quantum dots near a variety of Ag and Au nanoparticles. The photoluminescence excitation (PLE) spectrum of quantum dots closely follows the localized surface plasmon resonance (LSPR) scattering spectrum of the nanoparticles. We measure excitation enhancement factors of similar to 3 to 10 for different shapes of single metal nanoparticles.
