| Abstract: | Y_2O_2S long-lasting materials with the different Eu~(3+)molar ratio were synthesized by high-temperature solid-state method.The results showed that the samples were showing of yellow,orange,red,dark red when the Eu~(3+)content was 0%,5%,10% and 15% respectively.The samples were characterized by X-ray diffraction (XRD),scanning electron microscopy(SEM)and fluorescence spectroscopy(PL). |
