Abstract

Phonon modes of CdSe quantum dots in various glass matrices are investigated by Raman spectroscopy. The phonon energies are observed to be dependent on the host matrix as well as the quantum dot size. We have shown that the lattice contraction effect must be introduced to explain the observed differences of the phonon energies for CdSe quantum dots in the different glass matrices.
