摘要

量子点(QDs)为活性包覆纳米粒子(CNPs)的增益介质提供了一个令人兴奋的选择，因为它们具有巨大的增益系数，导致它们的极端限制效应。通过改变核/壳的相对尺寸，即有效地改变其带隙结构，可以调节核/壳量子点的光学性质。同样，CNP的共振可以通过改变其层的相对大小来调节。本文证明，通过在共振CNP结构内优化定位量子点，可以大大增强组合QD-CNP系统的固有放大行为。

The Performance of Active Coated Nanoparticles Based on Quantum-Dot Gain Media

Quantum-dots (QDs) provide an exciting option for the gain media incorporated in active coated nanoparticles (CNPs) because they possess large gain coefficients resulting from their extreme confinement effects. The optical properties of core/shell QDs can be tuned by changing the relative size of the core/shell, that is, by effectively changing its band gap structure. Similarly, the resonance of a CNP can be adjusted by changing the relative sizes of its layers. It is demonstrated here that by optimally locating the QDs inside a resonant CNP structure it is possible to greatly enhance the intrinsic amplifying behavior of the combined QD-CNP system.
