| Abstract: | The Eu 2+ and Dy 3+ codoped Sr 2MgSi 2O 7: Eu 2+ ,Dy 3+ blue emission long afterglow phosphor was synthesized and its photoluminescence properties were studied. It is known with the measurement method of X ray diffraction pattern that the luminescent material is an akermanite crystal. It is shown with the decay curve that its afterglow properties are better than the traditional (Ca,Sr)S:Bi blue long afterglow phosphor. Its decay curve is in accordance with the calculated results of the formula l... |
