Resonance Raman scattering from Cd1−xZnxS nanoparticles dispersed in oxide glass

Resonance Raman scattering from 1 and 2 LO phonons is investigated from Cd1−xZnxS nanoparticles dispersed in oxide glass before and after annealing. The resonance profiles are found to exhibit asymmetry which is attributed to the interference effects arising from a nonresonant contribution to the polarizability. The energies of the resonances are found to be consistent with the direct interband transition energies estimated from the reported optical data.
