Colloidal semiconductor quantum dots are materials with promising applications in flat panel displays, biosensors, quantum dot lasers, and optical communication elements. Many of the applications are novel and require firm understanding of the physical and chemical properties of quantum dots to optimise reliability and performance. To fulfil the technological promise of fluorescent quantum dots, problems relating to quantum yield and photostability urgently need to be resolved. These issues will be addressed through spectroscopic studies of single quantum dots both in vacuum and in condensed phases. Ultimately, the findings will guide rational design of nanoscale devices based on quantum dot luminescence.

胶体半导体量子点材料在平板显示器、生物传感器、量子点激光器、光通信器件等方面具有广阔的应用前景。许多应用是新颖的，需要对量子点的物理和化学性质有深刻的理解，以优化可靠性和性能。为了实现荧光量子点的技术承诺，迫切需要解决与量子产率和光稳定性有关的问题。这些问题将通过在真空和凝聚相中的单量子点的光谱研究来解决。最终，这些发现将指导基于量子点发光的纳米器件的合理设计。
