Abstract

Pressure-Raman spectra are compared for bulk crystalline 68Zn 76Se and ZnSe nanorods. The broadening of TO(γ) and LO(γ) is explained by multiphonon mixing and the position of a gap in the 2-phonon DOS. Nucleation of the phase transition in 68Zn 76Se leads to striking similarities in the Raman spectra of retrieved bulk and nanorod samples.
