| 摘 要： | Bright long afterglow phosphorescence glasses were prepared by using SrAl2O4： Eu^2＋, Dy^3＋ phosphors and suitable glass frits together. The SrAl2O4： Eu^2＋, Dy^3＋ phosphors were initially prepared by the solid reaction method. Three kinds of glass frits were prepared to match the SrAl2O4： Eu^2＋, Dy^3＋ phosphors. Effects of the compositions of the glass frits, the ratios of the phosphors to the frits us well us the firing temperature and firing times on the properties of the samples were discussed. XRD analysis indicated the samples exhibited the typical diffraction peaks of SrAlwO4： Eu^2＋, Dy^3＋. The emission spectra of the samples showed broad bands peaking at 510nm.The excitation spectra of the samples showed broad bands ranging from 300 to 480hm. These are believed due to the 5d4f-4f transitions of Eu^2＋ in the SrAl2O4： Eu^2＋, Dy^3＋ phosphors. The afterglow luminescence of the samples excited by a 40W fluorescence lamp for 30min can be observed in the dark for more lOh with the naked eyes. It can find wide applications in many fields.

| Abstract: | Bright long afterglow phosphorescence glasses were prepared by using SrAl2O4: Eu2 , Dy3 phos- phors and suitable glass frits together. The SrAl2O4: Eu2 , Dy3 phosphors were initially prepared by the solid reaction method. Three kinds of glass frits were prepared to match the SrAl2O4: Eu2 , Dy3 phosphors. Effects of the compositions of the glass frits, the ratios of the phosphors to the frits as well as the firing temperature and firing times on the properties of the samples were discussed. XRD analysis indicated the samples exhibited the typical diffraction peaks of SrAl2O4: Eu2 , Dy3 . The emission spectra of the samples showed broad bands peaking at 510nm.The ex- citation spectra of the samples showed broad bands ranging from 300 to 480nm. These are be- lieved due to the 5d4f-4f transitions of Eu2 in the SrAl2O4: Eu2 , Dy3 phosphors. The afterglow luminescence of the samples excited by a 40W fluorescence lamp for 30min can be observed in the dark for more 10h with the naked eyes. It can find wide applications in many fields. |
