The spectral properties of Ce3+ doped M3MgSi2O8(M=Sr, Ba) pyrosilicates at 298K and 77K were studied. Under UV light excitation, Ce3+ doped M3MgSi2O8(M=Sr, Ba) pyrosilicates phosphors emit efficient bluish violet light. In the M3MgSi2O8(M=Sr,Ba) system the emission spectra of Ce3+ ions consist of the emission bands of the transitions from the Ce3+ 5d --> F-2(5/2) and 5d --> F-2(7/2) levels, Ce3+ ions can substitute for Sr2+ or Ba2+ ions, and then form two different emission centers, respectively, according to the order from Sr2+ to Ba2+ ion, with ionic radius increases, the spectrum of this phosphor slightly shifts to short wavelength and the emission intensity decreases.
