| Abstract: | Y2O2S: Eu3 ,Mg2 ,Ti4 red long-lasting powders were synthesized by high-temperature solid-phase method.The effects of citric acid on luminescence properties of Y2O2S: Eu3 ,Mg2 ,Ti4 were studied.The results showed that the luminescence properties of Y2O2S: Eu3 ,Mg2 ,Ti4 could be improved by adding a certain amount of citric acid;the initial brightness was 1 800 mcd/m2 and the afterglow time was 8 h.The samples were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM) and fluorescence spectroscopy(PL). |
