摘要：
We report the resonant Raman scattering of the optical phonon in Ge nanocrystals with radius ranging from 2 to 5 nm. We have observed the effect of quantum confinement on both the optical phonon and the E-1 exciton. The confinement energy of the E-1 exciton has been explained within the effective mass approximation.
