Abstract

Abstract: Ba2 La2.85- x Tb0.15 Sm x (SiO4 )3 F (BLSOF:0.15Tb 3+, x Sm 3+ ) is a polychromatic phosphor with an apatite structure that was manufactured through a solid-state process. X-ray diffraction (XRD) and a scanning electron microscope (SEM) were utilized to examine the phosphor's phase and morphology. Using the Rietveld technique, the as-prepared phosphor structure was validated. By progressively raising the doping contents of the samarium, the phosphors emitted multicoloured luminescence from short to long wavelengths as indicated by analysis of the optical performance. Overall, the data provide strong evidence that the transfer of energy in BLSOF:0.15Tb 3+, x Sm 3+ is responsible for the phosphor's colour-tunable property. Graphical abstract: The left graph shows the photoluminescence spectra of the Ba2 La3 (SiO4 )3 F:0.15Tb 3+, x Sm 3+ phosphors, in which the energy transfer behavior occurs from Tb 3+ to Sm 3+ . And this results in these phosphors could emit typical multicolor light such as green, yellow, and reddish color with increasing doping contents of samarium as shown in the right graph. Image 1 Highlights: Ba2 La2.85- x (SiO4 )3 F:0.15Tb 3+, x Sm 3+ phosphors were prepared for the first time. Energy transfer mechanism from Tb 3+ to Sm 3+ is quadrupole-quadrupole interaction. The color of phosphors could be adjusted from green, yellow to reddish colour.
