Both the required calcination temperatures and heating duration were markedly reduced as compared with the solid-state reaction. With a rise in the calcination temperatures, the emission intensity of Ce3+-doped phosphors decreased due to the thermal quenching effects. For Tb3+-doped phosphors, the emission intensities of the splitting peaks were influenced by the thermal interaction between the Tb3+ energy levels. It is found that the Ce3+- and Tb 3+-doped SrSi2O2N2 phosphors demonstrate great absorption in the vacuum ultraviolet region and are therefore suitable for application in plasma display panels. While Ce3+ and Tb3+ were codoped into SrSi2O2N2, the emission spectra exhibited the combination of the Ce3+ and Tb3+ emission peaks. The energy transfer process from Tb3+ to Ce3+ via the electrostatic interaction was also investigated in detail. ? 2011 The American Ceramic Society.[SDGs]SDG7journal article10.1111/j.1551-2916.2011.04469.x2-s2.0-80053961874https://www.scopus.com/inward/record.uri?eid=2-s2.0-80053961874&doi=10.1111%2fj.1551-2916.2011.04469.x&partnerID=40&md5=8468359fa5cd18595695ffc81cf04c4e
