Nanocrystallites vibration modes of CdS<i>x</i>Se1−<i>x</i> semiconductors in glasses: Size determination by Raman scattering

Abstract

Nanocrystallites eigenmodes of CdSxSe1−x semiconductors are observed by low frequency inelastic scattering and the diameters ranging between 2.5 nm and 9 nm are determined. This new application of Raman scattering is a powerful tool to study quantum size effects in these nonlinear optical materials.
