Cadmium-free one-dimensional colloidal nanocrystal heterostructures

该项目的目标是开发创新的胶体纳米晶体异质结构，为环保光电器件和光催化以及其他先进应用提供基础。一维半导体纳米晶体具有理想的电子和催化性能（线性极化发射，大吸收截面，降低激光阈值，改善电荷分离和输运）。然而，目前对这些材料的研究主要局限于剧毒的硫族镉。本项目旨在探索一类具有理想性能的无镉胶体纳米晶体异质结构。该项目旨在研究它们的生长机制、性质和效果，以支持产品开发，并推进纳米级电子学的基础知识。

The goal of this project is to develop innovative colloidal nanocrystal heterostructures to provide the basis for eco-friendly optoelectronic devices and photocatalysis as well as other advanced applications. One-dimensional semiconductor nanocrystals have desirable electronic and catalytic properties (a linearly polarised emission, large absorption cross section, reduced lasing threshold and improved charge separation and transport). However, present investigations of these materials are mainly limited to highly toxic cadmium chalcogenides. This project aims to explore a family of cadmium-free colloidal nanocrystal heterostructures with the desired properties. The project intends to investigate their growth mechanisms, properties and effects to support product development and advance the fundamental knowledge of electronics at the nanoscale.
