| Abstract: The phosphor of stronium mctasilicate co-activated with Eu3+ and Bi3+ ions synthesized firstly in this paper.The variety of emitting intensity of it with the concentrations of Eu3+ and Bi3+ has been studied.It was found that the compound with the formula Sr0.87Li0.0915SiO3: Eu0.0753+,Bi0.01653+ gave the strongest fluorescence.The stimulating mechanism of Bi3+ ion on Eu3+ has been also discussed.The excitation and emission spectra of the phosphors,SrSiO3: Eu3+ and SrSiO3: Eu3+,Bi3+ were given and their crystal structures were also determined in this paper. |
