Tunable color emission based on the activator shell thickness of multilayer core–shell nanoparticles under double NIR excitation

Abstract

Rare earth luminescent nanomaterials are hot topic due to their unique fluorescence properties. Effective spectral regulation could be achieved by adjusting the coating thickness to affect the energy transfer process in core–shell structure.

One-step fabrication of Cu-based metal organic framework multilayer core–shell microspheres for efficiently catalyzing the oxygen reduction reaction

“…The core can be inorganic nanoparticles, 14 metal oxides, 13,15 silica, 16 polymers, 3,17 metal organic frameworks (MOFs) [18][19][20] and so on. The shells are usually reduced graphene oxide, 7 metal sulfides, 21 ternary compounds, 22 rare earth elements, 23 esters, 24 chitosan 25 and so on. Generally, it is very difficult to fabricate MCS-M/NMs with a consistent composition.…”
