Dalton Transactions, 2013•pubs.rsc.orgRare-earth doped Ca2SnO4 phosphors were synthesized using a conventional solid state
reaction method. The red phosphorescence of Eu3+ was observed in this system with
persistence time. In the as-prepared samples, the doped rare earth ions occupied both Ca
and Sn sites in the host lattice. The longest phosphorescent persistence property can be
achieved for the Ca2SnO4 phosphors with a 0.1% Eu dopant. Depending on the doped rare
earth ions, afterglow emissions of various colors were observed.
