They exhibit an amorphous SiO 2 core and a crystalline luminescent shell. Zn2SiO 4:Mn2+ and Ca10(PO4) 6OH:Eu3+ shell materials are investigated. The influence of the doping concentration on optical and structural properties was studied. The resulting nanoparticles were characterized by X-ray diffraction analysis, transmission electron microscopy, inductively coupled plasma optical emission spectrometry, and photoluminescence spectroscopy.en666620conference paper
