Abstract
In this paper, the luminescence properties of SrB4O7 : xEu, yTb phosphors were investigated. The SrB4O7: xEu, yTb phosphors were first synthesized in air atmosphere, and the emission spectra of Eu2+, Eu3+ and Tb3+ ions have been observed in phosphors. We found that the relative intensity of the emission of Eu2+ ion in the same matrix are increased when Tb3+ is incorporated in SrB4O7: Eu phosphor. So the valence state of europium is influenced by terbium. These phenomena can be explained using an electron transfer theory.
