Abstract
An efficient purplish-blue phosphor Ca3MgSi2O8:Ce3+ has been synthesized. T he emission and excitation spectra of the Ce3+ ions in Ca3MgSi2O8 at 298 an d 77 K indicate that there are two kinds of Ce3+ emission centers. Accordin g to the analysis of the crystal structure of the host and the spectral pro perties, we have demonstrated that the two kinds of emission centers corres pond to Ce3+ substituting into two different octa-coordinated Ca3+ sites in the host, respectively.
