PROBLEM TO BE SOLVED: To provide a phosphor for an electron beam-exciting light-emitting element, safe, low price, causing no charge-up at low acceleration voltages and having high luminous brightness, to provide a method for preparing the same, and to provide the electron beam-exciting light-emitting element.;SOLUTION: The phosphor is obtained by containing, in Ca₁₂Al₁₄O₃₃ or Sr₁₂Al₁₄O₃₃ matrix, predetermined amounts of at least one element selected from a group consisting of Mn, Sn, Pb, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Bi as an activator, and at least one metal selected from a group consisting of Zn, In, Sn, Cr, Mo, Os, Re, Nb, V, W, Sm, Ir, Ru, Nd, La and Ti as an electroconductive metal. The phosphor is prepared by ordinary firing. The light-emitting element comprises the phosphor.;COPYRIGHT: (C)2007,JPO&INPIT
