Colloidal quantum dots (CQDs) have useful absorption and emission properties but exist in inhomogenous batches. Solution photon correlation fourier spectroscopy (S-PCFS) combines interferometry with fluorescence correlation spectroscopy (FCS) to measure the spectral correlation of the average single fluorophore in a solution. With S-PCFS, the intrinsic emission linewidth of CQDs can be assessed. This linewidth information is related to phonon coupling and gives insight into the separation of holes and electrons in excited CQDs. Experimental considerations and recommendations for troubleshooting a S-PCFS apparatus are also presented here.
