The luminescent properties of Eu2+ doped, Tb3+ doped and Tb3+/Eu2+ co-doped high silica glass were investigated. The emission and excitation spectra of such glass samples were measured and compared. The spectra of Tb3+/Eu2+ co-doped sample’s is no equaled the superposition of the two single-doped glass samples’. A possible mechanism was discussed to explain that.
