Carrier Temperatures in CdSe Quantum Dots using Detailed Balance Method

We are taking a new approach to the controversial topic of the Phonon Bottleneck. Using a conventional Fluorescence Spectrophotometer and UV-Visible Spectrophotometer (made by Varian Labs) and the Bolton and Archer equation we are able to determine the carrier temperatures of electrons in CdSe quantum dots at a range of excitation wavelengths. The carrier temperature data will allow us to better understand some of the odd behaviors of the excited pair of electron and hole in the quantum dots. We plan on an expansion of this data to determine a dependence on solvent, time, quantum dot size, and various organic shells around quantum dots on the carrier temperature measurements. The end result should be an argument on one side or another of the Phonon Bottleneck debate.
