Abstract
An afterglow lamp has a light emitting section for converting electric energy to optical energy. A fluorescent layer is excited to emit-light by the light emitting section and is represented by the general formula (M.sub.1-p-q, Eu.sub.p Q.sub.q)O.multidot.n(Al.sub.1-m B.sub.m).sub.2 O.sub.3 .multidot.kP .sub.2 O.sub.5 .multidot..alpha.X. The values of p, q, n, m, k, .alpha. and .alpha./n are in the ranges 0.0001.ltoreq.p.ltoreq.0.5, 0.0001.ltoreq.q.ltoreq.0.5, 0.5.ltoreq.n.ltoreq.3.0, O.ltoreq.m.ltoreq.0.5, O.ltoreq.k.ltoreq.0.2, O.ltoreq..alpha..ltoreq.0.5, and O.ltoreq..alpha./n.ltoreq.0.4. M is at least one selected from a group of divalent metals including Mg; Q is a coactivator and at least one selected from a group including Mn, Zr, Nb, Pr, Nd, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; and X is at least one selected from halogen elements.
