• illustrates that the shape of the PCS spheres was conserved during pyrolysis. Figure 4B shows SiC-Acr spheres synthesized from PCS/acrylic acid. The carboxylate groups were used for molecular binding of ceria [36]. Although a CeO2 shell cannot be seen on SEM pictures, the EDX-analysis of the discrete spheres

• have been described for carboxylate complexes of Eu(III) [21]. The fluorescence spectrum of the modified silica shows a distinct shoulder at around λem.≈ 515 nm. This indicates a complex radiative relaxation of the formed transition metal species, the fluorescence originating from at least two
