Abstract

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 → ²F_5/2 and 5d → ²F_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.
