Luminescence

Luminescent Properties of CaMgSi2O6-Based Phosphors Co-Doped with Different
Earth Ions. — The title materials with long afterglow are synthesized by solid
46- 009 Rare
state reaction from mixtures of CaCO3, 4MgCO3·Mg(OH)2·5H2O, SiO2, and
Ln2O3 (Ln: Eu, Dy, Nd) using small quantities of H3BO3 as a flux (1200 °C, 4 h). Both
afterglow intensity and persistent afterglow time of CaMgSi2O6:Eu,Dy are better than
those of CaMgSi2O6:Eu and CaMgSi2O6:Eu,Nd, which is in agreement with the results
of thermally stimulated luminescence curves. — (JIANG, L.; CHANG*, C.; MAO, D.;
