Electron energy-loss spectroscopy (EELS) is widely used to study the composition and electronic structure of materials at the nanometre scale. The low-loss region of the EEL spectrum (< ~50 eV) is of particular interest for the study of optical properties. Examples of the applications of EELS to measure the optical properties of individual nanopartlcies, including quantum dots will be presented. Comparison to calculations of optical properties and EEL spectra using density functional theory will be given.
