  • Long afterglow luminescent material and its manufacturing method
    Patent number: 7686979
    Abstract: A long afterglow luminescent material of the formula aMO.bM? (S?Se1-?).cAl2O3.d B2O3.eP2O5: xEu.yLn, wherein M is/are selected from Sr, Ca, Ba, and Mg, and any combinations thereof; M? is/are selected from Sr, Ca, and Ba, and any combinations thereof; Ln is/are selected from Nd, Dy, Ho, Tm, La, Ce, Er, Pr, Bi, and Sm, and any combinations thereof; a, b, c, d, e, x and y are mole ratios, wherein 0.5<a<6.0, 0.0001?b?2.0, 0.5?c?9.0, 0?d?1.0, 0?e?1.0, 0.00001?x?0.25, 0.00001?y?0.3, 0???1.0, 0.5<(a+b)?6.0, 0<(d+e)?1.0. The preparation process thereof is a high temperature solid-state reaction comprising an oxidation stage and a subsequent reduction stage.
