title: [Luminescence properties of Ba2MgSi2O7 : RE].
abstract: In the present paper, alkaline earth silicates Ba2MgSi2O7 : RE were prepared under a reducing atmosphere by solid-state reaction. Under UV light excitation, Ce3+ doped pyrosilicates phosphors emit efficient bluish violet light. The emission spectra of Eu2+ doped pyrosilicates phosphors showed that Eu2+ ions could occupy two types of sites in Ba2MgSi2O7 host. The energy transfer from Ce2+ to Eu2+ in Ba2MgSi2O7 is efficient, as there is a large overlap between Ce3+ emission bands and Eu2+ excitation bands. Analysis of the spectra of Ce3+ and Tb3+ co-doped phosphor indicated the existence of energy transfer from Ce3+ to Tb3+ in Ba2MgSi2O7 under UV excitation.
