摘要：

Low frequency inelastic scattering (LOFIS) concerns Raman scattering of light below 100 cm-1; in this frequency range the eigenmodes of small crystallites give rise to low frequency lines whose position depends on the crystallite sizes. LOFIS of various CdS(x)Se1-x semiconductor-doped glasses was analysed and diameters between 2 and 10 nm were obtained. Resonance effects strongly enhanced the longitudinal optical (LO) phonons. The influence of confinement on the scattering of light by LO phonons is discussed.
