Yn. Hwang et al., EFFECT OF LATTICE CONTRACTION ON THE RAMAN SHIFTS OF CDSE QUANTUM DOTS IN GLASS MATRICES, Physical review. B, Condensed matter, 54(21), 1996, pp. 15120-15124
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.
