The present invention provides a new ultra-long after-glow phosphorescent material and manufacturing method for the same. The said materials comprise a phosphor consisting of a MS · b M 3 (PO 4 ) 2 · c MSiO 2 · d MO · f Al 2 O 3 · x RO · y TR 2 O 3 · z MnO, where the M is Ca, Mg, Ba, Sr, Zn or combinations thereof; The R is Eu, Sm, Yb, Pr and Nd or combinations thereof;the TR is La, Y, Nd, Dy, Er, Tu,Ce, Ho or combinations thereof; and, a, b, c , d, f, x, y , z is the number of mol. The said phosphorescent material has superior water resistance and temperature resistance. |
