Abstract

Abstract : A series of samples with quaternary CdS 1 − x − y Se x Te y nanocrystals with cations of three types distributed over nanocrystal lattice sites were grown in a borosilicate glass matrix by the diffusion-limited growth technique. Their Raman spectra confirm the three-mode compositional behaviour of CdS 1 − x − y Se x Te y phonon spectra. The compositional dependence of the LO phonon frequencies is analysed experimentally for a series of samples containing nanocrystals withx ≈ y .
