Single-nanorod spectroscopy at low temperature is used to study the exciton states of individual CdSeZnS core-shell nanorods. By analyzing the LO-phonon assisted recombination the authors may distinguish between charged and exchange-splitted excitons. Four different types of single-nanorod emission spectra are found and assigned to neutral, positively, and negatively charged excitons and multiexciton states. The spatially separate confinement of two localized excitons in one, individual nanorod is discussed.
