Luminescent properties of a new long afterglow Eu2+ and Dy3+ activated Ca3MgSi2O8 phosphorJournal of The European Ceramic Society, 21
Long afterglow Sr 2 MgSi 2 O 7 (SMS) phosphor was prepared by Douby's methods at high temperature and reductive atmosphere. The excitation and emission spectra of this phosphor showed that both had broad bands and that the main emission peak at 469 nm was due to 4f‐5d transitions of Eu +2 and implied that the luminescence centres Eu +2 occupied the Sr +2 sites in the Sr 2 MgSi 2 O 7 host. The phosphor doped only with Eu ions did not demonstrate the long afterglow phenomenon, but when co‐doped with Dy +3 ions in the SMS matrix, significant long afterglow was observed.
