摘要

胶体量子阱纳米结构（QWs）是光电子器件的潜在材料，如发光二极管和激光器。采用胶体法制备了CdS/CdSe/CdS和CdS/CdSe/ZnS量子阱，并对其进行了表征。瞬态吸收光谱显示了传统核壳量子点与量子阱、CdS/CdSe/CdS与CdS/CdSe/ZnS量子阱之间不同的动态过程。基于Marcus理论和量子约束效应建立了模型来解释实验结果。

Exciton Dynamic Processes in Colloidal CdS/CdSe/CdS Quantum Well Nanostructures

Colloidal quantum well nanostructures (QWs) are potential materials for optoelectronic devices, such as light-emitting diodes and lasers. CdS/CdSe/CdS and CdS/CdSe/ZnS QWs were produced within a colloidal method, on which characterizations were conducted. The transient absorption spectra showed different dynamic processes between the traditional core/shell quantum dots and QWs, as well as between CdS/CdSe/CdS and CdS/CdSe/ZnS QWs. Models were built on the basis of Marcus theory and quantum confinement effect to explain the result of the experiment.

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
