摘      要：With stable physical properties, the rare-earth silicate phosphor of MgSiO3：Mn2＋,Nd3＋ is one of the suitable luminescent materials used in preparing functional fibers. In order to promote the afterglow properties of red-emitting phosphors, we prepared it by means of solid-state reaction, and the effect of manufacturing elements including H3BO3 and environmental factor of calcining temperature, type of flux on its luminescence property were investigated through evaluating their afterglow properties. The results showed that with the concentration of Nd3＋ increasing, the amounts of H3BO3 doping and calcining temperature, the afterglow time and initial brightness of the rare-earth silicate phosphor increased and then decreased gradually. The afterglow properties of different flux concentration were different from one to another as： H3BO3〉Na＋〉K＋〉No flux.
