摘要

Sr1–xPrxAl2B2O7 (0.005 ≤ x ≤ 0.04) red-emitting phosphors were prepared by firing in air at 950°C for 6 h. Using the XRD technique, the structural characterization of the prepared materials was examined. Additionally, FTIR was used to examine the Al–O and B–O bond characteristics in the crystal structure. Finally, using a spectrofluorometer, the luminescence property of Sr1–xPrxAl2B2O7 (0.005 ≤ x ≤ 0.04) was thoroughly examined at ambient temperature. The prepared SrAl2B2O7 materials with varying Pr3+ doping emitted radiation at three wavelengths in the red region (609, 622, and 645 nm) when exposed to 469-nm light.
