Photoluminescence Properties of K1-xSr4(BO3)3∶xPr3+ Phosphors Prepared by High-Temperature Solid-State Method
Luminescent materials of K1-xSr4(BO3)3∶xPr3+ are successfully prepared with the high-temperature solid-state method. The X-ray diffraction patterns show that the synthesized sample has a symmetrical structure of Ama2 space point group. The scanning electron microscopy analysis results show that the sample has good dispersion degree and crystallinity although its appearance is irregular and fluffy. When the doped mole fraction of Pr3+ is 1%, the light intensity of the sample reaches the maximum. The absorption and diffuse reflection spectra are well enantiomorphous with excitation and emission spectra.
