Synthesis and optical properties of luminescent core–shell structured silicate and phosphate nanoparticles

Monodisperse, luminescent core–shell structured inorganic nanoparticles were synthesized by sol–gel technology. They exhibit an amorphous SiO 2 core and a crystalline luminescent shell. Zn 2SiO 4:Mn 2+ and Ca 10(PO 4) 6OH:Eu 3+ shell materials are investigated. The influence of the doping concentrat...

Beschreibung
Zusammenfassung:Monodisperse, luminescent core–shell structured inorganic nanoparticles were synthesized by sol–gel technology. They exhibit an amorphous SiO 2 core and a crystalline luminescent shell. Zn 2SiO 4:Mn 2+ and Ca 10(PO 4) 6OH:Eu 3+ 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.
