Luminescent properties of β-Lu2Si2O7：RE^3＋ （RE=Ce, Tb） nanoparticles by sol-gel method
Nanoscale RE^3＋ （RE=Ce, Tb） doped and codoped lutetium pyrosilicate Lu2Si2O7（LPS） phosphors were prepared by using the sol-gel method. Heat treatment was performed in the temperature range from 900 to 1100 ℃. The crystal structure was analyzed by X-ray diffraction （XRD）. The results showed that the...

| Summary: | Nanoscale RE^3＋ （RE=Ce, Tb） doped and codoped lutetium pyrosilicate Lu2Si2O7（LPS） phosphors were prepared by using the sol-gel method. Heat treatment was performed in the temperature range from 900 to 1100 ℃. The crystal structure was analyzed by X-ray diffraction （XRD）. The results showed that the β-type structure of LPS was obtained at 1100 ℃. The excitation spectra in the UV and VUV ranges and the emission spectra of the samples were measured at room temperature, and their luminescent properties were studied. The energy transfer from Ce^3＋ to Tb^3＋ in the codoped samples were observed and discussed. |
