Characterization of Nanocrystal Size Distribution Using Raman Spectroscopy with a Multi-particle Phonon Confinement Model

We demonstrate how to determine the size distribution of semiconductor nanocrystals in a quantitative manner using Raman spectroscopy employing an analytically defined multi-particle phonon confinement model. Results obtained are in excellent agreement with the other size analysis techniques like transmission electron microscopy and photoluminescence spectroscopy.
