CdS, CdS/ZnSe core/shell, and CdS/CdZnS-ZnCdSe/ZnSe core/intermediate/shell nanoparticles. Type–II core/shell nano-heterostructures. Detailed study on temperature-dependent photoluminescence and Raman-scattering spectra. Intermediate layer plays an important role in reducing lattice strain, improving the PL quantum yield.
