Previous Experimentation on Quantum Dots

From here the software is used to record an emission Spectra that looks something like the image below.

Another possible experiment is through the use of various glass filters, each filter having a different size quantum dot. By find the absorption spectra one can determine the quantum dot band gaps and radii. The experiment would look something like the image below.

The results from each filter should look like the following image here.

A very useful equation in determining the size of a quantum dot can be seen below.
