Abstract:
The present invention provides a new ultra-long after-glow phosphorescent material and manufacturing method for the same. The materials include a phosphor including aMS.bM3(PO4)2.cMSiO3.dMO.fAl2O3.xRO.yTR2O3.zMnO, where the M is Ca, Mg, Ba, Sr, Zn or combinations thereof; The R is Eu, Sm, Yb or combinations thereof; the TR is La, Pr, Y, Nd, Dy, Er, Tm, Ce, Ho or combinations thereof: and a, b, c, d, f, x, y, z is the number of mol. The phosphorescent material has superior water resistance and temperature resistance.
