| Abstract: | Na3La9B8O27:Ln3+(Ln=Eu or Tb)phosphors have been prepared by solid state reaction,sol-gel process technique and fluxes technique,respectively.The optimal initial ratios have been determined in the solid state reaction process.The excitation and emission spectra of Na3La9B8O27:Eu3+ and Na3La9B8O27:Tb3+ are measured and explained.The different photoluminescent efficiency of the various prepared phosphors is studied and discussed.The phosphors fabricated by fluxes technique have the most luminescent efficiency... |
