Article Synopsis
- Exciton-phonon coupling affects the clarity of light emitted from nanocrystals, making it important to study this phenomenon.
- This research involves single-particle spectroscopy experiments on various colloidal nanocrystals at approximately 10 K to analyze exciton-phonon interactions.
- The results reveal that the intensity of phonon replicas is linked to charge-carrier distribution, with quantum mechanical calculations suggesting that surface charges play a significant role.
Cation exchange is known to occur during the synthesis of colloidal semiconductor heteronanoparticles, affecting their band gap and thus altering their optoelectronic properties. It is often neglected, especially when anisotropic heterostructures are discussed. We present a study on the role of cation exchange inevitably occurring during the growth of anisotropic dot-in-rod structures consisting of a spherical ZnSe core enclosed by a rod-shaped CdS shell.
