(a) The luminescence processes in sensitizer and emitter co-doped nanoparticle. (b) The energy transfer kinetic processes from sensitizer to emitter in the case of core/active-shell structure.
(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.
PL spectra of model A and B. The spectra are normalized by the numbers of the nanoparticles.
PL spectra of the NaYF4:Ce3+, Tb3+/NaYF4: x% Ce3+ colloidal solutions (0.1 M).
