| Abstract: | In this paper, the fluorescent properties of DyxTbyY1-x-yP5O14 crystals have been investigated. An important difference with TbxTbyY1-x-yP5O14 crystals is that the 5D3-7FJ transitions of Tb3+ ions are quenched at low concentration and 5D4-7FJ transitions of Tb3+ ions are sensitized because the Dy3+ presents in crystals. The reason is that the 5D3-5D4 transition of Tb3+ and the 6H15/2-6H11/2 transition of Dy3+ produce the cross relaxation, in addition to the 7F8-7F0 transition of Tb3+.We compared the fluorescent intensities between Tb0.1Dy0.1Y0.8P5O14 and Tb0.1Dy0.1Y0.9P5O14 crystals, it was found that the fluorescent intensities of Tb0.1Dy0.1Y0.8P5O14 crystals was much stronger than Tb0.1Dy0.1Y0.9P5O14 crystals in the same condition. When the Tb3+concentration is constant, the fluorescent intensities of Tb3+ decrease with the increase of Dy3+ concentration |
