Temperature Dependence of Red Long Afterglow from Y2O2S：Eu, Ti, Mg

Temperature Dependence of Red Long Afterglow from Y2O2S：Eu, Ti, Mg

At low temperature, some long-lasting phosphors could not work well in practical applications. So it is necessary to investigate the temperature dependence of the phosphors. The Y2O2S.Eu, Ti, Mg microcrystalline samples were prepared by solid state reaction method. Phosphors were sintered at 1150 ℃...

Zusammenfassung:At low temperature, some long-lasting phosphors could not work well in practical applications. So it is necessary to investigate the temperature dependence of the phosphors. The Y2O2S.Eu, Ti, Mg microcrystalline samples were prepared by solid state reaction method. Phosphors were sintered at 1150 ℃ for 20 min in air, putting in and taking out both at high temperature. The emission spectra and the afterglow spectra as well as the thermoluminescence curve were measured for Y2O2S：Eu,
