Bi3+/Ln3+-Codoped Boroaluminate Phosphors with Tunable Multicolor Emission for Multidimensional Luminescence Readout and UV-Shielding.
Combining lattice regulation of crystal-field-sensitive Bi3+ emission with Bi3+ → Ln3+ sensitization provides two complementary pathways for tuning the luminescence of single-host phosphors. Herein, Bi3+-activated Sr6Lu1-yYyAl(BO3)6 solid solutions and Bi3+/Ln3+-codoped Sr6LuAl(BO3)6 (SLAB; Ln = Eu, Dy, Sm, and Tb) pho...
