Spectroscopy of single quantum dots
Grant number: DP0451651
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..View full description
