Writing a feature article based on the impacts of core@shell structures on different properties such

(Arik Kar, et al. Nanoscale, 2012, 4, 3608): In this contribution, we have highlighted the new development and current status of rare earth (RE) based core@shell nanocrystals. We have addressed the impacts of core@shell structures on the properties of lanthanide based nanocrystals including crystal phase, lattice strain, downconversion emission, upconversion emission and energy transfer. We have described some general synthetic methodologies to design RE based core@shell nanostructures. An interesting finding reported is that the local environment of an ion in the core@shell structure significantly affects the modifications of radiative and nonradiative relaxation mechanisms. In this feature article, we have attempted to identify the critical parameters governing the design of luminescent lanthanide based core@shell nanostructures.
