摘要：
Luminescence intensity of CdS:Mn/ZnS core-shell quantum dots (QDs) can be strongly enhanced in comparison with bulk CdS:Mn and nanoparticles, while the luminescence due to the surface state is greatly suppressed by a capping ZnS shell. We find that with the increasing temperature, the peak position of CdS: Mn/ZnS core-shell QDs blue shifts due to the reduction of phonon coupling. Unlike the bulk CdS: Mn, the luminescence of the core-shell QDs is less sensitive to thermal quenching.
