Quantum Dots Module
- Intended for the physical chemistry laboratory
- Students prepare CdSe quantum dots using techniques given elsewhere
(J. Chem. Educ, 82, 1697, 2005)
- Absorption and fluorescence spectra are collected under a range of
preparation conditions that vary the size of the dots (larger dots
results in a longer wavelength absorption feature)
- The spectra are compared with that predicted by a simple model.
We are still working out a method for determining the size of the dots
using the portable STM.
