Zusammenfassung:A yellow-green silicate long persistence luminescent material and its production are disclosed. The chemical formula is aSrO. bCaO. cMgO. dSio2. eB203.Eux.Lny; Ln is lanthanide element except Eu, it reinforces persistent effect; a, b, c, d, e, x and y are mol coefficients, proportion of a: b: c: d: e: x: y is 1: 0.2-5: 0.3-15: 0.4-20: 0.01-1: 0.001-0.1: 0.001-1 mol. It has high brightness, fast reactive speed under weak-light excitation condition, stable chemical property and various applied environments.
