Abstract
Phonon modes of CdSe quantum dots in various glass matrices are invest igated by Raman spectroscopy. The phonon energies are observed to be d ependent on the host matrix as well as the quantum dot size. We have s hown 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.
