摘    要:The luminophors of four kinds of alkaline earth meta-silicates doped with Eu~3 and/or Bi~(3 )ion(s)weresynthesized and the luminescence properties of Bi~(3 )and Eu~(3 )ions were studied.The regularities that Me(Ⅱ)ions affect the luminescence of Eu~(3 )ion sensitized by Bi~(3 )ion were investigated.The optimum composition andsynthesis condition were obtained.The absorption and emission peak are situated at 283 and 353nm with theoptimum concentration 0.02 mol of Bi~(3 )in CaSiO_3:Bi.In CaSiO_3:Bi,the optimum concentration of Bi~(3 )is0.007 mol and that of Eu~(3 )is 0.040 mol.For all of the alkaline earth ions concerned in MeSiO_3:Eu,Bi,theBi~(3 )can sensitize the Eu~(3 )and the Me(Ⅱ)ions in host and make a great difference in the adsorption hand ofBi~(3 )ion.by exciting Bi~(3 )ion,the emissions are from both Eu~(3 )and Bi~(3 )ions and the best sensitization effectis achieved when Me(Ⅱ)is Sr.
