摘要： Sr3.96Al14O25:Eu2+,Dy3+ long persistent materials with different weight of H3BO3 prepared by the high temperature solid-state reaction method were characterized by X-ray powder diffraction (XRD), scanning electronic microscope (SEM), photoluminescence spectra (PL), and thermoluminescence (TL). The results of XRD indicate that the 3% addition of H3BO3 is in favor of the formation of pure phase Sr4Al14O25, and SrAl12O19 was generated when H3BO3 is in low content or high content. The average grain sizes of samples grow bigger during the increasing of H3BO3. PL spectra show that the emission peak does not shift evidently and the emission intensity changes a little, indicate that the different amount of H3BO3 have a little inference to the crystal field. The decay characteristics and TL measurement show that H3BO3 affect the afterglow properties of Sr3.96Al14O25:Eu2+,Dy3+, because the increasing of H3BO3 lead to more defects in Sr4Al14O25 matrix.
