    摘要: A phosphorescent phosphor according to the present invention includes a matrix of formula MAl₂O₄ in which M is a metal selected from calcium, strontium and barium, or in which M comprises at least two metals selected from calcium, strontium, barium and magnesium. The phosphor matrix may be doped with europhium as a activator, and optionally other rare earth metals as co-activator(s).
