“…So glass ceramic, as the glass and crystal composites, has attracted strong interests for their excellent luminescence * Corresponding author. properties, machinability, high uniformity and stability [12,13]. In numerous glass ceramic systems, silicate system is one of the best choices for its good thermal stability and physicochemical property, the previous reports have shown the outstanding luminescence properties and long afterglow phenomenon of Ca 2 MgSi 2 O 7 :Eu 2+ , Dy 3+ [14], CaMgSi 2 O 6 :Eu 2+ , Dy 3+ [15].…”
