Abstract

The distinctive fluorescent properties of semiconductor nanocrystal quantum dots (QDs) make them advantageous for use in optoelectronic and biological applications. We report on experiments done to characterize the optical properties and the general photostability of CdTe QDs with varying ZnS shell thicknesses. Steady-state and time-resolved absorption and fluorescence spectroscopy measurements indicate that increasing the ZnS shell thickness results in longer absorption and emission wavelengths, increased quantum yield, and improved photostability.
