(a) The PL spectra and the corresponding photographs of bare core NPs (I), inert-shell coated NPs (II) and active-shell coated NPs (III); (b) The UV-vis absorption spectra of these three NPs with the energy level diagrams of the core/active-shell NPs (insert). All the solutions are normalized by the numbers of nanoparticles.
