Abstract

Pb2+ and Mn2+ co-doped Zn2SiO4 phosphors were prepared by hydrothermal treatment using mesoporous silica as template and silicon source. The reaction temperature is reduced due to the mesoporous structure of mesoporous silica, and the large specific surface area of mesoporous silica is in favor of the uniform doping of ions. The effect of Pb2+ on the structure and morphology of Zn2SiO4:Mn2+ was investigated through various analytical techniques. Excitation and emission spectrum analysis reveals that the increased luminous intensity of Mn2+ ions is detected by ion co-doping, which is caused by energy transfer from the Pb2+ ion to the Mn2+ ion..
