Mesoporous SiO2/Zn2SiO4:Eu3+ hollow nanospheres were successfully synthesised via the combination of layer-by-layer and combustion technique. The structures and morphologies of as-obtained SiO2/Zn2SiO4:Eu3+ nanospheres were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N2 adsorption–desorption isotherms techniques. SiO2/Zn...
