摘要：

Eu3+ or Gd3+ doped P-SiO2 and two ions co-doped P-SiO2 were synthesized by hydrothermal method. Under the excitation of ultraviolet light the spectral behaviour and the composition dependence on luminescence properties of Eu3+ and Gd3+ in P-SiO2 were studied. The energy transfer of Gd3+ -> Eu3+ in P-SiO2 was observed. Energy transfer process and mechanism are analysised, the mechanism of energy transfer from Gd3+ to Eu3+ is a resonant transfer, in which electric dipole-dipole interaction plays a leading role.
